Abstract
Mobility and diffusivity of degenerate hot electrons itinerant two-dimensionally in quantum wells are studied including the effect of electron-electron interactions. Occupancy of the first two subbands and lattice scattering via deformation potential acoustic and polar optic modes are considered. The degeneracy of the distribution function is found to affect the diffusivity more significantly than mobility. At large sheet carrier concentrations inter-subband scattering lowers the mobility as well as the diffusivity.
