Vicky Johnson,Roger Hart,Jennifer Colwellate ballistically until reflected by some sort of a boundary — either the sample edge or some other introduced sharp fluctuation in the potential. In the GaAs/GaAlAs heterojunction systems, it is relatively easy to attain mobilities high enough so that mean free paths are micometers or more. It is a

Laura Camfield (Senior Lecturer)inrich ., 1988; Reed and Kirk, 1989). Structures such as electron waveguides and quantum point contacts are excellent laboratories to study fundamentals of electronic transport in the quantum ballistic regime. The creation of 3-dimensionally confined systems (“quantum dots”) (Hansen ., 1990; Reed .,

However, many fundamental problems on non-equilibrium carrier transport still remain to be clarified

Marlene Morrison,Sheila Gallowayations, such as the drift-diffusion equation). Powerful Monte Carlo techniques have been developed to solve the BE (for a review see e.g. Jacoboni and Reggiani, 1983), and combined with Poisson equation solvers these methods form the basis for the theoretical analysis and design of modern semiconduc

For instance, disorder induced corrections arise from quantum interference and electron-electron interaction, generally lowering the conductivity. The interference arises beca

In many cases an explicit description of the contact properties is crucial for making contact with experimental reality. A theory of electrical conductance which is capable of treating contacts is the transmission approach. The transmission approach relates th
