Spin-photocurrent in p-SiGe quantum wells under terahertz laser irradiation

V. V. Bel'kov, S. D. Ganichev, Petra Schneider +7

A detailed study of the circular photogalvanic effect (CPGE) in SiGe structures is presented. It is shown that the CPGE becomes possible due to the built-in asymmetry of quantum we…
