Transport, Quantum Interference and Localisation in Ultrathin Systems with Randomly Corrugated Walls and Interfaces

Abstract

Comparative effects of elastic scattering by random surface inhomogeneities and bulk impurities are discussed for ultrathin quantised systems. A simple general surface collision operator is derived outside of the quantum resonance domain. Analytical and semi-analytical applications to corrugation-defined localisation and transport in various types of physical systems are presented.
