Dark current mechanisms in ultra-thin mid-wave infrared detectors Open
Mid-wave infrared photodetectors with ultra-thin (t<250nm) absorbers are characterized electrically and optically for a range of absorber doping concentrations. Negative differential resistance is observed in unintentionally doped absorber…

All-epitaxial resonant cavity enhanced long-wave infrared detectors for focal plane arrays Open
We demonstrate a monolithic all-epitaxial resonant-cavity architecture for long-wave infrared photodetectors with substrate-side illumination. An nBn detector with an ultra-thin (t≈350 nm) absorber layer is integrated into a leaky resonant…
