Paper Abstract

Cool hole effect on hot electron energy relaxation dynamics in GaAs quantum wells grown on Si was investigated using photoreflectance and time-resolved photoluminescence spectroscopies. It was demonstrated that for the quantum wells in which there is a two- dimensional light (heavy) mass hole gas the electron energy relaxation is dominated by electron-hole (electron-longitudinal optical phonon) energy exchange.
