Hole-acoustic phonon energy loss rates in GaAs quantum wells determined by light scattering.
01 January 1988
We report a determination of energy loss rates of free holes in GaAs quantum wells. The hot hole temperatures were obtained from stokes and antistokes inelastic light scattering spectra. In the temperature range dominated by acoustic phonon interactions we find that the hole energy loss rate is proportional to the square of the hole temperature.
