Paper Abstract

The unipolar barrier photodetector architecture such as the nBn provides an effective means for lowering generationrecombination dark current by suppressing Shockley-Read-Hall processes, and for reducing surface leakage dark current. This has been especially beneficial for III-V semiconductor based infrared photodiodes, which traditionally tend to suffer from excess depletion dark current and the lack of good surface passivation. Advances in bulk and type- II superlattice infrared absorber materials have provided continuously adjustable cutoff wavelength span ranging from 2 to 14 μm and beyond, greatly expanding the limited coverage provided by traditional bulk III-V infrared detectors based on InGaAs and InSb. In this work we discuss recent developments of antimonide-based extended-SWIR, MWIR, and LWIR detectors and focal plane arrays at the NASA Jet Propulsion Laboratory.
