Anisotropic dimensional effects in semiconductors and semimetals
Abstract
Theoretical and experimental research on anisotropic dimensional effects is reviewed. The dimensional dependence of electrical conductivity and magnetoresistance in large slabs (on the order of diffusion lengths), and nonlinearity of electrical conductivity in relatively weak fields, carrier redistribution in strong fields (accompanied by prodigious changes in total carrier number and by production of domains, depletion layers, and enrichment layers), electromagnetic excitation of sound in semimetals, and anisotropic dimensional effects in association with the skin effect (altering the surface impedance of semimetals by a whole order of magnitude) are among the topics reviewed. Intervalley carrier distributions and many-valley crystals are also discussed.
