Abstract

The photoconductive (PC) detectivity of longwave infrared (LWIR) HgCdTe detector at low and very low temperature is calculated, and it can be concluded that detectivity limit is related to parameters of material, it is restricted by both specifications of material as well as device and application requirement of IR system. Natural limit and technical limit of PC detectivity of LWIR HgCdTe at liquid nitrogen temperature zone is presented.
