Optical orientation of electron spins in GaAs quantum wells
S. Pfalz, R. Winkler, T. Nowitzki +4
We present a detailed experimental and theoretical analysis of the optical orientation of electron spins in GaAs/AlAs quantum wells. Using time and polarization resolved photolumin…

Traces of stimulated bosonic exciton-scattering in semiconductor luminescence
D. Haegele, S. Pfalz, M. Oestreich
We observe signatures of stimulated bosonic scattering of excitons, a precursor of Bose-Einstein-Condensation (BEC), in the photoluminescence of semiconductor quantum wells. The op…
