摘要
For zero temperature we present theoretical results for the mobility of a two-dimensional electron gas on the surface of silicon (111) in the case of impurity scattering and compare with experiments. We use a two-band model (7K-model) for valley degeneracy g(v) = 2 and 4, which was proposed recently in the literature. A comparison between theory and recent experimental results shows reasonable agreement. Within the two-band model we predict the magnetoresistance in a parallel magnetic field and the Dingle temperatures of the two bands as function of the carrier density. (c) 2007 Elsevier B.V.
