ABSTRACT
We have optimized low-temperature-grown In0.3Ga0.7As for use in ultrafast photoconductive devices. Using low temperature ex situ annealing techniques, we have produced a photoconductive material that is highly resistive (∼104 Ω cm), has sub-500 fs carrier trapping lifetimes, and is matched to 1.06 μm laser excitation.
