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 Programm Quant mech Intro ... Technology Solids are classified according to their properties as either insulators, conductors, or semiconductors based on the number of charge carriers in the conduction band and hence their ability to support current flow: Insulators do not permit current flow because the separation between their valence and conduction bands is too large to allow an electron to be promoted into the conduction band where it could take part in conduction. (only a few thousand conduction electrons per cm Conductors allow current to flow easily because of the large number of conduction electrons (10 per cm ) available. In conductors the energy bands overlap making it possible for very small energies to liberate the electrons where they then participate in current flow. Semiconductors are classified between conductors and insulators (with approximately 10 carriers per cm ). A few electrons appear in the conduction band, with an equal number of holes in the valence band, enabling limited conduction. The energy separation between the valence and conduction bands in semiconductors can be overcome by thermal, electrical, or chemical excitations to name a few. Because of the widespread use of semiconductor devices in electronics (A p-n junction and a transistor being the basic components of any system) precise analysis of their properties is crucial.
