Barrier InAsSb/B-AlSb LWIR detector for FSO: theoretical assessment

InAsSb ternary alloy is considered to be an alternative to HgCdTe (MCT) in long-wavelength infrared (LWIR) spectral region. The high operation temperature conditions are successfully reached with A^IIIB^V bariodes, where InAsSb/AlAsSb system is playing dominant role. Since theoretically there is no depletion region in the active layer, the generation-recombination and trap-assisted tunneling mechanisms are suppressed leading...
