Abstract
Abstract
GaSb-based nBn IR photodetectors were grown by MBE using a metamorphic buffer process on 6-inch diameter GaAs and Si substrates. M-nBn epiwafer characteristics and diode performance, including high quality full FPA imagery, will be presented and compared to the same nBn grown on native GaSb.

Abstract
Abstract
Unlike conventional detectors that rely on photocurrent, the open circuit voltage photodetector architecture relies on a detector operating in zero bias. The output from the detector is coupled to the gate of a FET in sub-threshold region. Radiometric characterization of this detector will be discussed.
