Spin noise spectroscopy in GaAs
M. Oestreich, M. Roemer, R. J. Haug +1
We observe the noise spectrum of electron spins in bulk GaAs by Faraday rotation noise spectroscopy. The experimental technique enables the undisturbed measurement of the electron…

Anomalous Spin Dephasing in (110) GaAs Quantum Wells: Anisotropy and Intersubband Effects
S. Doehrmann, D. Haegele, J. Rudolph +3
A strong anisotropy of electron spin decoherence is observed in GaAs/(AlGa)As quantum wells grown on (110) oriented substrate. The spin lifetime of spins perpendicular to the growt…

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…
