Inter-Subband Optical Absorption in an Inversion Layer on a Semiconductor Surface in Tilted Magnetic Fields

摘要

Considerable progress has been made in our studies of Faraday rotation and other magneto-optical phenomena in MOS (metal-oxide-semiconductor) systems. These studies have also led to three interesting spin-off investigations: (a) multiple-reflection effects (we pointed out a discrepancy between two existing models and we generalized the correct model as a basis for enabling us to consider such effects in MOS systems), (b) magneto-transmission in an electron inversion layer of finite thickness (which enables us to obtain a recipe for the calculation of the surface conductivity), and (c) absorption of radiation propagating obliquely in a magnetoplasma. Progress is briefly reviewed.
