摘要

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 R$-0$/A values of Hg$-0.7$/Cd$- 0.3$/Te p infrared detectors at 100 K, and Hg$-0.78$/Cd$-0.22$/Te p 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 R$-0$/A values used in this calculation were obtained by simultaneously including generation-recombination, diffusion and tunneling mechanisms.!19
