Abstract
The frequency dependence of responsivity and detector noise for (Hg,Cd)Te detectors operating in the 8-14 pm region at 77°K was investigated. The results showed that these quantities have the same frequency dependence and corner frequency. Values of f* were thus experimentally determined and found to be >10 MHz for detectors that have D*X - 5 X 1010 cm Hz% Watt-1. The results are shown to be consistent with a simple photoconductive theory based on the assumption of equal lifetimes for holes and electrons.Keywords
