We report on the status of GaSb/InAs type-II superlattice diodes grown and fabricated at the Jet Propulsion Laboratory designed for infrared absorption in the 8-12μm range. Recent devices have produced detectivities as high as 8×1010 Jones with a differential resistance-area product greater than 6 Ohmcm2 at 80K with a long wavelength cutoff of approximately 12μm. The measured quantum efficiency of these front-side illuminated devices is close to 30% in the 10-11 μn range without antireflection coatings.
