摘要：

We present a fully quantum-mechanical analysis of phase-coherent electron transport in disordered semiconductor nanostructures. The analysis is based on a scattering matrix formalism which allows us to simulate the effects of interface roughness scattering, as well as scattering from point defects and defect clusters. Using this technique, we have studied quantum conduction in electrostatic Aharonov-Bohm interferometers and narrow ballistic constrictions of submicron dimensions.
