Abstract : This work was intended to explain basic questions related to long-wavelength InAsSb photodetectors. Can InAsSb be used for IR photodetectors operating at 200-300 K in the entire 8-14 micrometers region? What is the photoconductivity lifetime? What are limitations to the performance of InAsSb photoconductive and photovoltaic detectors? What are the limits? Can InAsSb compete with HgCdTe in applications for LWIR photodetectors? Demonstration of near room temperature 10.6 micrometers IR photodetector. What should be done to improve the performance further? How to obtain focal plane array. jg
