The utmost limit performance of interband cascade detectors optimized for the longwave range ofinfrared radiation is investigated in this work. Currently, materials from the III–V group are character-ized by short carrier lifetimes limited by Shockley-Read-Hall generation and recombination processes.The maximum carrier lifetime values reported at 77 K for the type-II superlattices InAs/GaSb andInAs/InAsSb in a longwave range correspond to ∼200 and ∼400 ns. We estimated theoretical detectivityof interband cascade detectors assuming above carrier lifetimes and a value of ∼1–50μs reported for awell-known HgCdTe material. It has been shown that for room temperature the limit value of detctivityis of ∼3–4×10¹⁰cmHz½/W for the optimized detector operating at the wavelength range ∼10μm couldbe reached.
