Paper Abstract

Calculations of free-carrier absorption in p-type semiconductor quantum wells as a function of carrier density, temperature and light intensity are reported. Valence band dispersions used in the calculation are obtained by a multi-band effective mass method which includes the effects of warping and heavy-light hole mixing. Carrier lifetimes are taken into account within the deformation potential approximation. Deviation of hole distribution from thermal equilibrium due to optical pumping is included in the calculation, and the saturation behavior is studied.
