    Abstract

    Electro-optic sampling of photoconductive transients on a subpicosecond time scale is used to study hot-carrier transport in GaAs. The results reported here are interpreted as direct time-domain observations of nonequilibrium transport on a subpicosecond time scale and they clearly show both an overshoot and bias-dependent delay at high excitation energy which are consistent with published Monte Carlo predictions.
