Hot carrier transient response in bulk III-V compounds

Abstract
A theory of transport of hot carriers in bulk III-V compounds is outlined. Equilibrium calculations are performed which show fair agreement with earlier Monte Carlo calculations and with experiment. Transient response calculations indicate velocity overshoot and it is seen that the mechanism primarily responsible for overshoot in these materials is repopulation, in contrast to the relaxation time mechanism observed in silicon. Calculations are performed for GaAs and other III-V compounds.
