Paper Abstract

The fluence of pulsed lasers of wavelength 4 and 10.6 microns necessary to induce one and two orders of magnitude temporary degradation in the R0A values of Hg0.7Cd0.3Te p/n infrared detectors at 100 K, and Hg0.78Cd0.22Te p/n infrared detectors at 40 K have been calculated. A nonparabolic energy-momentum relationship and temperature dependent energy gap of HgCdTe were used in this calculation. The R0A values used in this calculation were obtained by simultaneously including generation-recombination, diffusion and tunneling mechanisms.
