Recent investigations demonstrated that III-V-based nBn infrared detectors typically experience relatively significant performance degradation under 63 MeV proton irradiation due to displacement damage, limiting their viability for certain space-base

We report a Mid-Wavelength Infrared (MWIR) barrier photodetector based on the InAs/GaSb/AlSb type-II superlattice (T2SL) material system. The nBp design consists of a single unipolar barrier (InAs/AlSb SL) placed between a 4 µm thick p-doped absorbe

Noise spectra of type-II strained layer superlattice midwave infrared photodetectors were compared pre- and post-irradiation by a proton fluence of $\mathrm {7.5\times 10^{11}~ cm^{-2}}$ [total ionizing dose equivalent of 100 krad (Si)] and related t

Ongoing studies to characterize and improve the radiation tolerance of the quantum efficiency (QE) in III-V-based, unipolar barrier infrared detectors, such as nBn’s, require accurate knowledge of the detector QE damage factor. Here, results of suc

Type-II superlattices (T2SLs) of narrow-band-gap semiconductors hold great promise for mid- and long-wavelength infrared (IR) detectors. To improve photodiodes based on these superlattices, understanding of minority-carrier transport along the growth

To improve the performance of photodiodes based on narrow-bandgap InAs/GaSb type-II strained layer superlattices (T2SLs), knowledge of the vertical minority carrier transport is necessary. For this purpose, the key parameters influencing vertical min

Accurate p-type doping of the active region in III-V infrared detectors is essential for optimizing the detector design and overall performance. While most III-V detector absorbers are n-type (e.g., nBn), the minority carrier devices with p-type abso

Type-II Strained Layer Superlattice (T2SLS) infrared photodetectors have been in development over the last decade. T2SLS offers a theoretically longer Auger recombination lifetime than traditional mercury cadmium telluride (MCT), which presumably tra
