Is anybody can give me a detailed explanation or reference why the small bandgap IR detectors (eg. InSb photodetecotr) need to work in the cryogenic temperature?
In addition, anybody knows what is carrier capture time? Since some article said the photodetector detectivity is proportional to the square root of the carrier capture time, so increased capture time have the potential for higher temperature operation. Any thought? Thanks.
