中文摘要	hot electrons excited from the valence band by linearly polarized laser light are characterized by certain angular distributions in momenta. owing to such angular distributions in momenta, the photoluminescence from the hot electrons shows a certain degree of polarization. a theoretical treatment of this effect observed in the photoluminescence in quantum wells is given, showing that the effect depends strongly on heavy and light hole mixing. the very large disparity between the experimentally observed and theoretically expected values of the degree of polarization in the hot-electron photoluminescence suggests the presence of random quasielastic scattering. the effects of such additional scattering and the presence of a perpendicular magnetic field are incorporated into the theory. it is shown that the measurements of the degree of polarization observed in the hot electron photoluminescence, with and without an applied perpendicular magnetic field can serve to determine the time constants for both lo-phonon inelastic and random quasielastic scattering. as an example, these time constants are determined for the experiments reported in the literature.
