Electrons Vacuum Tubes Conductors Quantum Mechanics Semiconductors Germanium Diodes The Point Contact Transistor ... The Chip Semiconductors Metal conducts electricity; rubber doesn't. Gold conducts electricity; Styrofoam doesn't. Most materials fall easily into one category or the other. Everyone knows, for example, that if you want a good wire you're going to make it out of copper, not plastic. But there's a whole group of materials that fall in between. Their conductivity is in between metals and insulators. And their conductivity can be modified transiently, by shining a light on them or injecting charges. They're known as semiconductors, and they first became interesting to physicists in the late 1920s. At first no one could figure out how they worked. Scientists once thought that certain atoms simply held onto their electrons more strongly than others. But as physicists got a better understanding of what an atom looked like, they understood what was really going on. Different kinds of atoms have different numbers of electrons swarming around them. These electrons can only sit in specific places around the atom. It's sort of like rows of seats in a theater-in-the-round: a few electrons get to sit in the first row around the stage, and when that's filled the next electrons sit in the next row and so on. Electrons in a filled row stay put just as in a theater it's harder to get out when you've got people sitting on each side of you. In an insulator, every row is completely filled. Consequently the electrons rarely move. No moving electrons means no electricity can pass through.

95. Semiconductor - Wikipedia, The Free Encyclopedia For information on how semiconductors are used as electronic devices, One ofthe main reasons that semiconductors are useful in electronics is that http://en.wikipedia.org/wiki/Semiconductor

Semiconductor From Wikipedia, the free encyclopedia. A semiconductor is a material with an electrical conductance that is intermediate between that of an insulator and a conductor A semiconductor behaves as an insulator at very low temperature, and has an appreciable electrical conductance at room temperature . A semiconductor can be distinguished from a conductor by the fact that, at absolute zero , the uppermost filled electron energy band is fully filled in a semiconductor, but only partially filled in a conductor. The distinction between a semiconductor and an insulator is slightly more arbitrary. A semiconductor has a band gap which is small enough such that its conduction band is appreciably thermally populated with electrons at room temperature, whilst an insulator has a band gap which is too wide for there to be appreciable thermal electrons in its conduction band at room temperature. For information on how semiconductors are used as electronic devices , see semiconductor device Contents Fundamental semiconductor physics Band structure of a semiconductor Doping of semiconductors Intrinsic and extrinsic semiconductors ... edit Fundamental semiconductor physics edit Band structure of a semiconductor Band structure of a semiconductor showing a full valence band and an empty conduction band. The Fermi level lies within the forbidden bandgap

INSTITUT FÜR SCHICHTEN UND GRENZFLÄCHEN (ISG) ISG-Homepage Our four institutes Semiconductor Thin Films and Devices Ion Technology ... Unsere vier Institute Research Centre Juelich - MBE Group More screenshots ... WinGreen is a simulation package for transport calculations in layered semiconductors. Based on realtime Green's functions it provides a quantum mechanical approach for the description of dynamic and kinetic properties of interacting many-particle systems in a thermodynamic nonequilibrium state. The Coulomb interaction between charged particles is calculated via a Hartree selfconsistent single-particle potential employing the Poisson equation and the charge density from the Green´s functions. At the moment scattering (phonons, impurities, interface roughness etc.) is incorporated by means of an optical potential which is an empirical parameter. The material layer sequence is formulated on the basis of localized atomic orbitals with material dependant inter-layer coupling matrices. This tight binding approach provides an accurate model of heterointerfaces. WinGreen is an integrated simulation environment which allows a quick and convenient generation of simulation jobs, manages the computation process and provides plotting functions to display the simulation results. All material parameters are stored in ASCII format material databases which can be easily customized. The simulator is capable of generating output for the selfconsistent potential, the quantum charge density, the local density of states, the current density, the transmission probability and the bandstructure of zincblende type materials. In this version, multi-band outputs are supported but should be considered experimental.

Semiconductors Several elements are semiconductors, the most important being silicon. Semiconductors have special electronic properties which allow them to be insulating or conducting depending on their composition. Semiconductors also have special optical properties when exposed to electricity or light. Semiconductors can be made into transistors which can store a digital (on or off) signal. Transistors are used in all electronicscomputers, calculators, stop watches, amplifiers, etc. Semiconductors can also be made to emit light by exposing them to an electric field (light emitting diodes (LEDs) and diode lasers). Semiconductors are used in computers (45%), consumer products (23%), communications equipment (13%), manufacturing industries (12%), automobiles (5%), and by the military (2%). Semiconductors make up a huge, and growing, industry worldwide with billions of dollars in sales by semiconductor companies in North America, Europe, and the Asia-Pacific region. The Department of Materials Science and Engineering at has an active semiconductor research program led by Professors Thompson Ast , and Blakely Transistors Ceramics and Glasses Composites ...
