Subpicosecond photoconductivity overshoot in gallium arsenide observed by electro‐optic sampling

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.
