Experimental Separation of Rashba and Dresselhaus Spin-Splittings in Semiconductor Quantum Wells
S. D. Ganichev, V. V. Bel'kov, L. E. Golub +9
The relative strengths of Rashba and Dresselhaus terms describing the spin-orbit coupling in semiconductor quantum well (QW) structures are extracted from photocurrent measurements…
Resonant inversion of the circular photogalvanic effect in n-doped quantum wells
S. D. Ganichev, V. V. Bel'kov, Petra Schneider +7
We show that the sign of the circular photogalvanic effect can be changed by tuning the radiation frequency of circularly polarized light. Here resonant inversion of the photogalva…
Spin-galvanic effect due to optical spin orientation
S. D. Ganichev, Petra Schneider, V. V. Bel'kov +13
Under oblique incidence of circularly polarized infrared radiation the spin-galvanic effect has been unambiguously observed in (001)-grown -type GaAs quantum well (QW) structure…
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 sensitive bleaching and monopolar spin orientation in quantum wells
S. D. Ganichev, S. N. Danilov, V. V. Bel'kov +5
Spin sensitive bleaching of the absorption of far-infrared radiation has been observed in -type GaAs/AlGaAs quantum well structures. The absorption of circularly polarized radia…
