Abstract

We show that the initial dynamics of resonantly excited excitons in quantum wells is controlled by several processes, such as radiative recombination, spin-relaxation of excitons, electrons and holes, and scattering between different momentum states of excitons. We present results of experiments designed to simultaneously probe these processes. By a unified analysis of the results we extract quantitative information about radiative, spin-relaxation and momentum- relaxation rates, obtaining a good physical understanding of the initial dynamics of non- equilibrium excitons.
