Hot-carrier enhancement of photorefractive space-charge fields in zinc-blende semiconductors.
We observe an order-of-magnitude enhancement of the photorefractive effect in undoped CdTe on ~1-ps time scales that is caused by an overshoot in the two-photon-produced Dember space-charge field associated with hot-carrier transport.
