Circular Photogalvanic Effect at Inter-Band Excitation in Semiconductor Quantum Wells
V. V. Bel'kov, S. D. Ganichev, Petra Schneider +7
We observed a circular photogalvanic effect (CPGE) in GaAs quantum wells at inter-band excitation. The spectral dependence of the CPGE is measured together with that of the polariz…
Experimental Separation of Rashba and Dresselhaus Spin-Splittings in Semiconductor Quantum Wells
