The activity of burden of such a revision is certainly much high and this would alert endorsement for the approaching probability of wasteful aspects as individuals would reason therefore supporting the sanctioning of the equivalent. Among brought up contentions in help to the authorization of these recreational medications is expanded government pay through assessment and the probability of controlling medication misuse.

History of the computer Essay Example For Students

History of the PC Essay For the most part, a PC is any gadget that can perform numerical Calculations even a calculator, a math device, or a slide rule. As of now, in any case, the term normally alludes to an electronic gadget that can utilize a rundown of directions, called a program, to perform estimations or to store, control, and recover data. Todays PCs are wonders of scaling down. Machines that once gauged 30 tons and consumed distribution center size rooms presently may weigh as meager as three pounds (1. lograms) and can be conveyed in a suit pocket. The core of todays PCs are incorporated circuits (ICs), once in a while called microchips, or essentially chips. These little silicon wafers can contain a huge number of tiny electronic parts and are intended for some particular activities: some control a whole PC (CPU, or focal preparing unit, chips); some perform a huge number of numerical tasks every second (math oprocessors); others can store in excess of 16 million characters of data one after another (memory chips). In 1953 there were just around 100 PCs being used in the whole world. Today a huge number of PCs structure the center of electronic items, and in excess of 110 million programmable PCs are being utilized in homes, organizations, government workplaces, and colleges for pretty much every possible reason. PCs come in numerous sizes and shapes. Unique reason, or committed, PCs are intended to perform explicit undertakings. Their activities are constrained to the projects incorporated with their microchips. These PCs are the reason for electronic mini-computers and can be found in a large number of other electronic items, including advanced watches (controlling planning, cautions, and shows), cameras (observing screen rates and opening settings), and cars (controlling fuel infusion, warming, and cooling and checking several electronic sensors). Universally useful PCs, for example, PCs and business PCs, are substantially more flexible in light of the fact that they can acknowledge new arrangements of guidelines. Each new arrangement of directions, or program, nables a similar PC to play out an alternate kind of activity. For instance, one program lets the PC demonstration like a word processor, another lets it oversee inventories, but then another changes it into a computer game. Albeit some universally useful PCs are as little as pocket radios, the littlest class of completely practical, independent PCs is the class called note pad PCs. These generally comprise of a CPU, information stockpiling gadgets called circle drives, a fluid precious stone showcase (LCD), and a full-size keyboardall housed in a solitary unit sufficiently little to fit into a folder case. Todays work area PCs, or PCs, are ordinarily more impressive than the colossal, million-dollar business PCs of the 1960s and 1970s. Most PCs can perform from 16 to 66 million activities for every second, and some can even perform in excess of 100 million. These PCs are utilized for family unit the board and individual diversion, yet additionally for the vast majority of the mechanized undertakings required by private ventures, including word handling, producing mailing records, following stock, and computing bookkeeping data. Minicomputers are quick PCs that have more prominent datamanipulating capacities than PCs and can be utilized all the while by numerous individuals. These machines are basically utilized by bigger organizations to deal with broad bookkeeping, charging, and stock records. Centralized computers are huge, incredibly quick, multi-client PCs that regularly contain complex varieties of processors, each intended to play out a particular capacity. Since they can deal with immense databases, can at the same time suit scores of clients, and can perform complex numerical activities, they are the pillar of industry, research, and college registering focuses. The speed and intensity of supercomputers, the quickest class of PC, are nearly outside human ability to grasp, and their capacities are consistently being improved. The most refined of these machines can perform almost 32 billion computations for each second, can store a billion characters in memory at once, and can do in one hour what a personal computer would take 40 years to do. Supercomputers achieve these velocities using a few propelled designing strategies. For instance, basic hardware is supercooled to about outright zero with the goal that electrons can move at the peed of light, and numerous processors are connected so that they would all be able to deal with a solitary issue at the same time. Since these PCs can cost a huge number of dollars, they are utilized basically by government offices and enormous research communities. PC advancement is quickly advancing at both the high and the low parts of the bargains range. On the very good quality, by connecting together systems of a few little PCs and programming them to utilize a language called Linda, researchers have had the option to beat the supercomputer. This innovation is called equal preparing and evades long stretches of inert PC time. An objective of this innovation is the formation of a machine that could play out a trillion computations for every second, a measure known as a teraflop. On the opposite finish of the range, organizations like Apple and Compaq are growing little, handheld individual computerized collaborators (PDAs). The Apple Newton, for instance, lets individuals utilize a pen to include manually written data through a touch-touchy screen and to send letters and faxes to different PCs. Scientists are at present creating microchips called advanced sign rocessors, or DSPs, to empower these PDAs to perceive and decipher human discourse. This turn of events, which will allow individuals in all callings to utilize a PC rapidly and effectively, vows to prompt an upheaval in the manner in which people impart and move data. Correspondence. PCs make all cutting edge correspondence conceivable. They work phone exchanging frameworks, arrange satellite dispatches and activities, help produce embellishments for motion pictures, and control the hardware in all periods of TV and radio stations. Neighborhood (LANs) connect the PCs in independent branches of organizations or colleges, and bigger systems, for example, the Internet, license modemstelecommunication gadgets that transmit information through phone linesto interface singular PCs to different PCs anyplace on the planet. Columnists and authors presently use word processors to compose books and articles, which they at that point submit to distributers on attractive plates or through phone lines. The information may then be sent legitimately to PC controlled typesetters, some of which really plan the design of printed pages on PC screens. Science and research. PCs are utilized by researchers and specialists from various perspectives to gather, store, control, and dissect information. Running reproductions is one of the most significant applications. Information speaking to a genuine framework is gone into the PC, and the PC controls the information so as to show how the characteristic framework is probably going to carry on under an assortment of conditions. Along these lines researchers can test new speculations and plans or can analyze a difficult that doesn't fit direct experimentation. PC supported plan, or CAD, programs empower specialists and draftsmen to structure three-dimensional models on a PC screen. Scientific experts may utilize PC recreation to plan and test sub-atomic models of new medications. Some reproduction projects can produce models of climate conditions to assist meteorologists with making expectations. Pilot training programs are important preparing apparatuses for pilots. Industry. PCs have opened another period in assembling and buyer item advancement. In the processing plant, PC helped assembling, or CAM, programs assist individuals with arranging complex creation plans, monitor inventories and records, run robotized mechanical production systems, and control robots. Devoted PCs are routinely utilized in a large number of items running from mini-computers to planes. Government. Government offices are the biggest clients of centralized servers and supercomputers. The United States Department of Defense utilizes PCs for several undertakings, including research, breaking codes, deciphering information from spy satellites, and focusing on rockets. The Internal Revenue Service utilizes PCs to monitor a huge number of assessment forms. PCs are likewise basic for taking the evaluation, keeping up criminal records, and different errands. Training. PCs have end up being important instructive apparatuses. PC helped guidance, or CAI, utilizes modernized exercises that go from basic bores and practice meetings to complex intuitive instructional exercises. These projects have become fundamental encouraging devices in clinical schools and military instructional hubs, where the themes are perplexing and the expense of human educators is incredibly high. Instructive guides, for example, a few reference books and other significant reference works, are accessible to PC userseither on attractive circles or optical plates or through different Telecommunication systems. Expressions and Entertainment. Computer games are one of the most well known utilizations of PCs. The continually improving designs and sound capacities of PCs have made them famous apparatuses for craftsmen and performers. PCs can show a huge number of hues, can create pictures far more clear than those of a TV, and can interface with different instruments and synthesizers. Painting and attracting programs empower craftsmen to make reasonable pictures and energized shows significantly more effectively than they could with progressively customary apparatuses. Local Americans and Aztecs EssayMagnetic-tape stockpiling gadgets are generally utilized together with hard plate drives on enormous PC frameworks that handle high volumes of onstantly evolving information.

Sacrifices for a Better Future Coursework - 1375 Words

Sacrifices for a Better Future (Coursework Sample) Content: NameInstitutionCourseDateSacrifices for a Better FutureI aim to evaluate the theme of sacrifice evident in the movie To Live by Zhang Yimou. According to the filmà ¢Ã¢â€š ¬s storyline, the main characters live in abject poverty following the loss of wealth in gambling and other political constraints. I intend to discuss the sacrificial concepts highlighted in the movieà ¢Ã¢â€š ¬s main characters in surviving as a family despite the dynamic changes from wealth to poverty (Choy 24). The emphasis of the evaluating is the main issue that has been used by the movie director in developing the different scenes and providing a comprehensive display of the ideas (Bustamante and Aleidine 72). The theme of sacrifice occurs in various issues. For example, when Fuguià ¢Ã¢â€š ¬s family decides to work and support each. The study develops an informed analysis of the sacrifices shown towards material wealth, political issues, and family relationships among other issues.AnalysisThe movieà ¢Ã¢â€š ¬s description of Fugui as once a wealthy person, whose devotion to succeed propelled his decision to serve in the countryà ¢Ã¢â€š ¬s forces, depicts the sacrifices embraced towards success. It is apparent that the characterà ¢Ã¢â€š ¬s decision to become an entertainer emanated from his perception that he had exposed his family to an unworthy lifestyle. Therefore, the sacrifice to pursue fortune as a musician in the local community emanates from his love and affection to ensure sustainability of his familyà ¢Ã¢â€š ¬s welfare. The initial phases could be argued as repercussions of actions that were done willingly since he through his gambling activities. On the contrary, the misfortunes revolved around his critical decisions to fend for material wealth in the various activities for the best of his familyà ¢Ã¢â€š ¬s future. Apparently, the inclusion of Fugui at the level of normal Chinese citizens in the 1940s provided an informative basis of predicting the overwhe lming sacrifices vulnerable to the Chinese men in the period. It is arguable that the poor sacrificed their property for the benefit of the government (74).The argument of sacrifice in society is evident through Fugui and Chunshengà ¢Ã¢â€š ¬s friendship, which compelled them to join the army and serving in different divisions for the benefit of their entire families and the country. The depiction of their former puppeteer occupation defines that the two characters were united to pursue meaningful and worthwhile activities in their lives. The illustrative scene of the film depicts that innocent people sacrificed their live course under the compulsory policies to join the army and contribute in different efforts of assistance during the war (Linder 291).The idea of sacrifice amongst the people prevails despite the fact that they did not have any form of military training and equipment. For example, during the time that they were serving in the army, their children, parents and other relatives had no knowledge of where they were. At the same time, there were harsh conditions including severe cold that killed most of them. The perception is that the practice prevailed as one of the sacrifices that the Chinese citizens made towards contributing to a better China that exists today (Doll 3). In an extensive review, it is evident that the circumstances were coined towards making the peasant Chinese citizens like Fugui.Despite the unfortunate position that Fugui and his wife Jiazhen face, the two parents sacrifice their ego and pursue other opportunities to earn a better lifestyle for their families. Such activities occur after they have lost everything to gambling, they are still forced to contribute towards the government through the little money they make from meager jobs (Choy 25). They did this with the understanding that they would face severe action from the government if they failed to contribute towards the government and its initiatives at the time.Secondly, his sacrifice not to name Fuguià ¢Ã¢â€š ¬s treachery in failing to contribute his wealth to the government is evident on his execution. It is evident that Longà ¢Ã¢â€š ¬er, the casino owner who was the mastermind behind Fuguià ¢Ã¢â€š ¬s financial woes and eventual family troubles, was executed for failing to contribute towards the government. He remained adamant that he would not contribute towards what was referred to as the "Peopleà ¢Ã¢â€š ¬s governmentà ¢Ã¢â€š ¬Ã‚ . Again, this is an indication of the nature in which the Chinese government during the 1940s was harsh towards the population while focusing on collecting revenues (Bustamante and Aleidine 76).Similarly, Longà ¢Ã¢â€š ¬erà ¢Ã¢â€š ¬s sacrifices are evident through his decision to scorch his properties rather than losing it to the unjust policies and regulations imposed by the government. The depiction of this exploitation and the sacrifices that the weak in the Chinese society made towards the development of the country is even more evident in the contrast with those in the urban areas. When Fugui returns home, his friend Chunsheng works for the government. He leads a better life and is still viewed as one who exploits the poor like his long-term friend Fugui and his family. Evidently, this is an indication that a gap existed between those in the government and the poor in the society (Choy 32). The distribution of resources within this community imposed inequalities since the poor remained, while the government elite continued enriching themselves at the expense of the peasants.More so, even after exploiting the poor in the society, the Chinese Communist party did not give direct benefits to the poor in return. When Fuguià ¢Ã¢â€š ¬s daughter Fenxia is about to give birth, they cannot find an experienced doctor to help with the process. All doctors have been sent away for hard labor (Doll 5). The sacrifice is attributed to the fact that they are viewed as over-educated and a threat toward s the government and the policies it makes. As a process, Fuguià ¢Ã¢â€š ¬s daughter passes on after losing too much blood. This is an indication of the primitive mentality that the Chinese government had adopted towards developing any policies that ...

Essay on Rousseaus Critique of Moliere - 647 Words

In Rousseau’s critique of Moliere, he sees Moliere as being a perfect author. Moliere incorporates betrayal and distortion to stir the emotions and gain our interest, as well as sympathy. Rousseau feels that Moliere doesn’t help society, instead, he harms it. The reason is because Moliere is bringing down the value of society by using politics and comedy together. People are starting to see their flaws as being acceptable due to the content they see in Moliere’s work. If the first thing that one learns about Rousseau is that he was a supporter of community, the second is almost always that that he was moralistically opposed to theater as destructive of community morals. The source for this judgment is the Letter to D’Alembert, a text†¦show more content†¦By quot;nothing is requiredquot; Rousseau means that our emotions have not life-consequences. It is, as it were, irresponsible to be an audience member, a bit as if one were on holiday from one’s everyday, common humanity. For Rousseau, this irresponsibility is associated with the experience of an isolation which keeps one from being at home with one’s self, a home which, he is at pains to show, can only be achieved with others. The source of this moral danger -- the danger of irresponsibility -- derives from a second more basic quality of theater. Theater is, inevitably almost, representation. Here Rousseau’s hostility to theater reflects and is reflecting in his hostility to representative sovereignty. Representation (on stage) requires interpretation of its audience, whereas a just political society was to be built from that which was so transparent in time and space that it could not be other that what it was. No matter what its subject theater cannot be common. And it cannot be the everyday -- it is the perfected, immortal, transcendent particular self, precisely that self that wants to overlook the common, more like a god than a human being. Rousseaus â€Å"Letter to dAlembert† reaches two apparently contradictory conclusions: that theater does, and does not affect a societys culture. These divergent results can be explained by Rousseaus argumentative

Graphene-semiconductor Schottky Junction

Question : Discuss about the Graphene - Semiconductor Schottky jucation? Answer: Introduction In modern electronics, the electronic properties of the material are controlled by the voltage applied externally. The carrier concentration is varied by the externally applied voltage causing an electric current to flow through the device and the effect is called the electric field effect (Bartolomeo and Di 1-58). The traditional material includes the silicon and the recent non-traditional materials include organic conductors and carbon nano tubes. Since the electric field effect in metals is screened at extremely short distances of 1nm, atomically thin metal films are required. The report discusses the Graphene-semiconductor Schottky Junction with its history, characteristics, types, band structure and properties, significance and their applications. History Graphene was synthesized from graphite oxide solution in 1962 by the organic chemist Peter Boehm. Its band structure was described by Phillip Wallace 15 years before its synthesis. University of Manchester physicists Andre Geim, Konstantin Novoselov, and their colleagues synthesized high quality graphene in a simple, quick and cheap method by peeling away weakly bound layers from bulk graphite with the tape and then gently rubbed those layers onto an oxidized silicon surface. Thus, it becomes possible to study the 2D material and also to control its fabrication and integration into devices. The contact between metals and semiconductors was first studied in 1874 when Ferdinand Braun probed a lead sulfide crystal with the point of the metal wire and observed free flow of current in only one direction (Li et al 46-51, 2743-748). The rectifier behavior was first demonstrated by Walter Schottky who realized that a potential barrier called Schottky barrier exists across the junction. In 1914, Ralph Hartsough at the University of Kansas observed rectification when he adjoined Carbon in the form of graphite and Silicon to form a point contact. In 1962, George Harman and Theodore Higier from the National Bureau of Standards found that graphite electrodes on p-type Silicon had the behavior of ohmic contacts. In 2009, Filippo Giannazzo of the National Research Council in Catania, Italy, and his colleagues prepared the first Schottky junction between graphene and SiC. They measured its barrier height using scanning current spectroscopy. In the subsequent year, Xinming Li and Hongwe i Zhu prepared graphene on-silicon Schottky junction using chemical vapor deposition. The rectification characteristics and photovoltaic performance were successfully demonstrated. In 2010, Andre Geim and Konstantin Novoselovwere awarded the Nobel Prize for their research experiments conducted on the two-dimensional material graphene. Few Layer Graphene (FLG) and its characteristics Graphene is a two-dimensional material in which a single layer of carbon atoms is densely packed into the ring structure of benzene. It is referred to as Few Layer Graphene (FLG) and the properties of carbon based materials like graphites, nanotubes etc., are described by the study of FLG. FLG films are atomically thin with high quality to ensure that 2D electronic transfer is ballistic at submicron distances (Novoselov 666-69; Supporting Online Material). A metallic field effect transistor is demonstrated using FLG. By changing the gate voltage, the conducting channel can be changed as both 2D electron and hole gases. Platelets of highly-oriented pyrolytic graphite (HOPG) of 1-mm thick are used to prepare the graphene films. FLG films upto 10m in size are prepared by repeated peeling of small mesas of HOPG. Figure 1 Graphene films Photograph of large multilayer graphene flake with thickness 3nm on top of an oxidized Si wafer Atomic Force Microscopy (AFM) image of single-layer graphene - dark brown corresponds to SiO2 surface Figure 1 represents the multilayer and single-layer graphene films. These films are processed into multi-terminal Hall bar devices placed on top of an oxidized Si substrate and gate voltage is applied. The electronic properties of FLG devices are different from that of the thicker multilayer graphenes and 3D graphite. Figure 2 Field effect of Few Layer Graphene (FLG) A Graphenes resistivity Vs Gate voltage for different temperatures for T=5, 70 and 300K for top to bottom curves respectively B - Graphenes conductivity Vs Gate voltage for T=70K C Hall coefficient Vs Gate voltage D Temperature Vs carrier concentration (open circles film in A; squares thicker FLG film; solid squares multi layer graphene Figure 2 shows the dependencies of Graphenes resistivity , conductivity and Hall coefficient on the gate voltage . The graph shows that exhibits sharp peak to several and at high it decays to 100 . On both sides of the resistivity peak, the conductivity increases linearly with and at the peak exhibits sign reversal. Also, it is indicated in the figure, there exists a small overlap between the valence band and conduction band. A surface charge density of is induced by the gate voltage and the position of Fermi energy is shifted. represents the permittivity of free space and represents the permittivity of , is the electron charge and refers to the thickness of the layer. For The shallow-overlap semimetal is transformed into conductor with either whole electrons or whole holes through a mixed state in which both holes and electrons are present by the electric field doping (Figure 2). Through magnetoresistance and field effect measurements, the carrier mobilities in FLG are measured and they found to vary from sample to sample between 3,000 and 10,000 The typical mean free path is Carbon nanotubes exhibit very high mobility and the multilayer graphenes exhibit higher mobilities upto 15,000 at 300K and 60,000 . The band overlap in FLG for different samples varies from 4 to 20 meV. Also, graphene has linear energy dispersion and carriers with nil mass. Different FLG devices exhibit the ratio of between 2.5 and 7 while for multilayer graphene, it is 1.5. The important characteristics that make graphene the best metal are Linear I-V characteristics Huge sustainable currents Offers ballistic transport Scalability to nm size Modest on-off resistance ratio Zero gap semi conductor in which there is a tiny overlap between the valence and the conduction bands The type (electron or hole) and density of carriers can be controlled by electric filed which is called ambipolar electric field effect. Higher electrons and hole concentrations of and higher mobilities upto 10,000 are induced by the applied voltage Graphenes band structure and properties The graphenes band structure is shown in Figure 3 Figure 3 Graphenes band structure Pure crystal with linearly dispersive valence and conduction bands that meet at discrete points at which Fermi level is present If graphene is doped, the Fermi level can rise or fall. The incident light is high enough to induce inter band transition and 2.3% of the light is absorbed by the crystal promoting an electron to the conduction band leaving a hole If the light energy is too low, only intra band transitions in the valence band occur The important property of the graphene material is that it exhibits electron mobility exceeding 10,000 when deposited on or Another important property of graphene is that it has no band gap. Hence it can absorb light across a broad spectrum from the UV to IR wavelengths. Because of the high density of the states of metal, the Fermi level of the metal is constant. But the Fermi level of the graphene may be tuned by applying appropriate bias voltage or chemically doping the material with impurities. Shining light on graphene also affects the position of Fermi level. The Schottky barrier height of the junction mainly depends mainly on the graphenes Fermi level. Graphene-semiconductor schottky junction and its characteristics Through metal semiconductor contact, two kinds of devices are produced. They are Ohmic junction and Schottky junction The ohmic junction devices are made from highly doped semiconductors in which the ratio between current and voltage follows ohms law. The Schottky junction devices are which are made from lightly doped semiconductors. They exhibit high current and low resistance in one direction and negligible current and high resistance in the other direction. The Fermi level differs for the metal and the semiconductor. This disparity causes electrons to flow from one to the other until their Fermi levels align. This charge transfer depletes a region of free charges inside the semiconductor interface leaving immobile positive charges. This causes the semiconductors valence and conduction bands to bend upward at the interface. At equilibrium, the Fermi levels have aligned. The discontinuities in the allowed energy states produce the Schottky barrier. The flow of electrons from the metal to the semiconductor is blocked by the Schottky barrier. The semiconductor materials used for creating Schottky junctions with graphene include 3D organics and inorganics, 2 layered semiconductors, 1D nanostructures and 0D quantum dots. This Schottky junction with graphene forms the building block of devices like photo detectors, solar cells, LEDs, chemical sensor etc., Also, graphene material is mechanically strong, elastic, chemically stable and thermally conductive (Larsen et al 38851-8858). It is best suited for sensing applications since every atom resides on graphenes surface and it offers the largest possible contact area with its environment. It is also compatible with standard thin film processing techniques. Figure 4 shows the Graphene-semiconductor schottky junction. Graphene n-type semiconductor Vacuum Level Figure 4 Graphene-semiconductor Schottky Junciton Graphene (gold) atop on the n-doped semiconductor (gray) that produces an electric field and one-directional current flow from one material to the othe Energy band diagram of graphene-semiconductor schottky junction; Graphene work function; - Semiconductor work function (energy difference between the vacuum level and Fermi level) - Schottky barrier height; - conduction band minimum; - valence band maximum When the contact is first established, electrons will flow from semiconductor to graphene and bend the bands in order to align Fermi levels Applications 6.1 Photo detector The optical properties of graphene are also tunable as the Fermi level. Due to high carrier mobility and ultra-broadband response to light, the graphene-semiconductor junction is an ideal photo detector. The device responds to input light quickly and it is also sensitive to faint light (Lv et al 1337-339). Electron-hole pairs are generated on light fall and they are collected in different parts of the circuit with an electric field. Figure 5 shows the graphene semiconductor photo diode. n-type semiconductor Graphene Graphene n-type semiconductor Figure 5 Graphene semiconductor photo detector When the incident photon energy exceeds the band gap electron-hole pairs are generated in the semiconductors depletion layer When the Schottky barrier height , the electron-hole pairs are generated in the graphene. By adjusting the schottky barrier height with appropriate band gap, the spectral range of optical signals detected by the schottky junction can be tuned When the incident photon energy is high, electron-holes are produced in the depletion layer of semiconductor as shown in Figure 5 (a). By adjusting the thickness of the layer, the number of charge carriers generated per photon or quantum efficiency can be adjusted. Metals reflect much of the light while graphene allows 98% of the light to pass through into the semiconductor. The barrier height can be improved by introducing an interfacial layer, generally an oxide layer, between graphene and semiconductor. The Signal to Noise ratio is improved by the reduction of dark current. The second mode is internal photo emission which is illustrated in Figure 5 (b). This is useful at long wavelengths like IR to which many semiconductors are insensitive at room temperature. The incident photons generate electron-hole pairs in graphene which then pass into the semiconductor and contribute to current. 6.2 Solar Cells The advantages of using graphene in solar cells over Si based solar cells are Improved Performance Reduction of the amount of materials and Simplified manufacturing process Graphene-silicon solar cell of 2cm dimension On exposed to sunlight, charge carriers (electron hole pairs) are generated in the semiconductor and separated by built-in potential created by the junction Figure 6 shows the Graphene-semiconductor solar cell. The first graphene-silicon schottky junction provided Power Conversion Efficiency of only 1.7% and later with improved method of doping graphene and stable junction, 15-20% conversion efficiency is attained (Ayhan et al 26866-26871; Wu et al 2486-2489). To maximize the amount of light penetrating into the semiconductor, anti-reflection coating such as titanium di oxide has to be added to the shiny reflective graphene-Si interface. 6.3 Other Applications Ideal graphene/n-type silicon (n-Si) Schottky junction diodes are fabricated and a new transport mechanism is demonstrated to describe the ideal diode behavior (Sinha et al 4660-664). The ideal Metal Graphene Semiconductor (MGS) ohmic contact was formed with contact resistance less than with low doped Si (Byun et al 63-66). Metal-semiconductor-metal (MSM) photodetectors based on graphene/p-type Si Schottky junctions are fabricated and characterized (An et al 1-5). The other major applications include sensors such as bio-sensors, gas sensors, strain-gauge, pressure sensors, chemi-sensors, fuel and solar cells. The application areas include health care, textiles and fabrics, bio-devices and electric power generation (Sharon et al 145-165; Bououdina et al 26-61) Conclusion Graphene is the 2-dimensional, crystalline allotrope of carbon. It is one of the incredible materials with atom thinness. Graphene finds its enormous applications in nano electronics, biological engineering, optical electronics, photo voltaic cells, energy storage etc., In this report, the history of Graphene, graphene semiconductor schottky junction, its characteristics, band structure, types including Few Layer Graphene (FLG) and properties are discussed. The applications are also elucidated. References Bartolomeo, Antonio Di.
