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 structure gyrotropic media resulting in asymmetry of photoexcitation and relaxation processes. Several applications of the effects are also considered.
