We report an experimental study of the excitonic spin relaxation dynamics in GaAs/AlGaAs Multiple Quantum Wells (MQW) presenting interface roughness by time and polarization resolved luminescence spectroscopy. The relaxation is found to occur mainly when the excitons are in the free state, before th

We report on the effect of photogenerated free carriers on the spectral diffusion and on the LO-phonon Raman scattering of resonantly excited excitons. This is observed by an exciton population redistribution between localized states and by a decrease in the Raman scattering intensity under an extre

We present the results of optical, steady-state and time-resolved studies of photoluminescence and photoluminescence excitation in high-quality Al 0.3 Ga 0.7 As/GaAs quantum wells in which the presence of large (larger than the exciton radius) atomically flat islands can be inferred, identical to th
