Abstract
The Coulomb mediated transfer of energy from hot electrons to cool holes can play an important role in the dynamics of photo-excited semiconductor plasmas. We demonstrate that in 3-dimensional systems, accurate modeling of the electron-hole scattering process should at least include the effects of valence band structure on the heavy and light hole wavefunctions. In addition to reducing the effectiveness of intra-valence band processes, the p-orbital nature of hole states also enables hot electrons to cool via inter-valence band hole transitions. Even when the split-off band and non-parabolicity effects are ignored, these latter processes contribute significantly to the net energy exchange rate and become increasingly important at high temperatures and densities.
