Scattering length — The scattering length in quantum mechanics describes low energy scattering. It is represented by the term a. General concept When a slow particle scatters off a short ranged scatterer (e.g. an impurity in a solid or a heavy particle) it cannot… … Wikipedia
Electron mobility — This article is about the mobility for electrons and holes in metals and semiconductors. For the general concept, see Electrical mobility. In solid state physics, the electron mobility characterizes how quickly an electron can move through a… … Wikipedia
Monte Carlo methods for electron transport — The Monte Carlo method for electron transport is a semiclassical Monte Carlo(MC) approach of modeling semiconductor transport. Assuming the carrier motion consists of free flights interrupted by scattering mechanisms, a computer is utilized to… … Wikipedia
Graphene — is a one atom thick planar sheet of sp2 bonded carbon atoms that are densely packed in a honeycomb crystal lattice. It can be viewed as an atomic scale chicken wire made of carbon atoms and their bonds. The name comes from GRAPHITE + ENE;… … Wikipedia
Coherent potential approximation — The coherent potential approximation (or CPA) is a method, in physics, of finding the Green s function of an effective medium. It is a useful concept in understanding how waves scatter in a material which displays spatial inhomogeneity. One… … Wikipedia
Drift velocity — The drift velocity is the average velocity that a particle, such as an electron, attains due to an electric field. It can also be referred to as Axial Drift Velocity since particles defined are assumed to be moving along a plane. In general, an… … Wikipedia
High-temperature superconductivity — Unsolved problems in physics What causes superconductivity at temperatures above 50 kelvin? High temperature superconductors (abbreviated high Tc or HTS) are materials that have a superconducting transition temperature (Tc) above 30 K… … Wikipedia
2DEG — A two dimensional electron gas (2DEG) is a gas of electrons free to move in two dimensions, but tightly confined in the third. This tight confinement leads to quantized energy levels for motion in that direction, which can then be ignored for… … Wikipedia
Muffin-tin approximation — Electronic structure methods Tight binding Nearly free electron model Hartree–Fock method Modern valence bond Generalized valence bond Møller–Plesset perturbation theory … Wikipedia
КОНУЭЛЛ-ВАЙСКОПФА ФОРМУЛА — определяет время т релаксации импульса носителей заряда в полупроводниках с энергией при их рассеянии на ионах примеси. Получена Э. Конуэлл и В. Вайскопфом в 1950. К. В. ф. имеет вид где е заряд электрона, диэлектрич. проницаемость кристалла, N… … Физическая энциклопедия
