摘要：

We resolve spatially, spectroscopically, and temporally the photoluminescence emission from single self-assembled InAs/GaAs quantum dots. The rich photoluminescence spectrum and its evolution with time after pulse excitation and with the density of excitation is experimentally measured and analyzed using a theoretical multiexciton model. The model accounts quantitatively for the dynamics of a small number of interacting electrons and holes confined in optically excited semiconductor quantum dots.
