Abstract
The quantum wave-guide strategy was applied to study the influence of surface scattering on quantum transport. It started from the time-dependent Schrödinger equation, then perturbation terms were obtained and the film conductance calculated via the kinetic equation. The sheet conductance of a thin metallic film, a spin-valve layered structure and a semiconductor quantum well were evaluated in different physical limits, in particular, for different roughness character, long wave roughness or ripples. The interplay between surface and bulk scattering was also considered. Various power laws for the conductance dependence upon film thickness were obtained. Qualitative agreement with available experimental data was achieved.
