Monopolar Optical Orientation of Electronic Spins in Semiconductors
S. A. Tarasenko, E. L. Ivchenko, V. V. Bel'kov +8
It is shown that absorption of circularly polarized infrared radiation due to intraband (Drude-like) transitions in n-type bulk semiconductors and due to intra-subband or inter-sub…
Spin-Galvanic Effect in Quantum Wells
S. D. Ganichev, E. L. Ivchenko, V. V. Bel'kov +6
It is shown that a homogeneous non-equlibrium spin-polarization in semiconductor heterostructures results in an electric current. The microscopic origin of the effect is an inheren…
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…
Optical Spin Orientation under Inter- and Intra-Subband Transitions in QWs
S. A. Tarasenko, E. L. Ivchenko, V. V. Bel'kov +8
It is shown that absorption of circularly polarized infrared radiation achieved by inter-subband and intra-subband (Drude-like) transitions results in a monopolar spin orientation…
