The contribution to the exciton linewidth in semiconducting quantum well structures due to the scattering of excitons by iree carriers is calculated. It is found that this contribution becomes very important in IImiting the exciton linewidth when a high density of free carriers is present or at low
A study of the process of exciton formation due to acoustic phonon interaction in quantum wells (QWs) is presented. Considering that excitons are formed from photoexcited free electron-hole pairs, we have derived the rate of such formation as a function of density and temperature of charge carriers
