Coulomb effects on quantum-well luminescence spectra and radiative recombination times

Abstract

A microscopic theory based on Bloch electrons and holes in a two-band approximation is applied in order to compute absorption and luminescence spectra for GaAs-type quantum wells at room temperature. Special focus is set to investigate the effect of the Coulomb interaction on the linewidth of the luminescence spectra and on the radiative recombination rates.
