The relaxation of hot photoexcited electrons is investigated in GaAs using an ensemble Monte Carlo approach, taking into account both the electron-hole interaction and the hot photon effect. Immediately after excitation by a 588-nm laser pulse, a considerable fraction of electrons transfers to the upper valleys instead of cascading down the central valley. It is shown that the model accounts for the observations.
