Magneto-gyrotropic effects in semiconductor quantum wells

Abstract

Magneto-gyrotropic photogalvanic effects in quantum wells are reviewed. We discuss experimental data, results of phenomenological analysis and microscopic models of these effects. The current flow is driven by spin-dependent scattering in low-dimensional structures gyrotropic media resulted in asymmetry of photoexcitation and relaxation processes. Several applications of the effects are also considered. PACS numbers: 73.21.Fg, 72.25.Fe, 78.67.De, 73.63.Hs 1 I.
