We report the strongly nonlinear dependence of indirect exciton photoluminescence (PL) kinetics on excitation density. In the indirect regime characterized by a slow exciton recombination, at high excitation densities, low magnetic fields, low temperatures, and for samples with small in-plane disord
The photoluminescence spectra of individual quantum dots have been measured with high spectral and spatial resolution spectroscopy. The temperature dependence of the line broadening is analyzed for different single-confined excitons. At low temperatures, the photoluminescence spectra can be very wel
