Mid-IR type-II InAs/GaSb nanoscale superlattice sensors
… However, there are some fundamental issues decreasing their performance and ability for high temperature operation, including fast Auger recombination rates and high thermal generation rate. These detectors operate at low temperatures (77K-200K) in order to obtain high signal to noise ratio. The …

InAs/Ga(In)Sb superlattice based infrared detectors using nBn design
… fields. The state-of-the-art photodetectors based on Hg1-xCdxTe (MCT) have large signal over noise ratio and their bandgap can be tuned to span 1-32 μm wavelength range. However, large tunneling and Auger dark currents due to low electron effective mass in MCT detectors require operation at …
