Interacting many-body systems in quantum wells: Evidence for exciton-trion-electron correlations

M. T. Portella-Oberli, V. Ciulin, J. H. Berney +3

We report on the nonlinear optical dynamical properties of excitonic complexes in CdTe modulation-doped quantum wells, due to many-body interactions among excitons, trions and elec…
