N2 - We have developed a computer program that simulates the electrical characteristics of a p + - n HgCdTe photodetector. Using solutions to the Poisson and Continuity equations we investigate low temperature behavior to determine optimum working conditions to enhance detectivity. Our model considers complete Fermi - Dirac statistics, major recombination mechanisms, band to band tunneling, trap assisted tunneling and impact ionization. Device performance was analyzed as a function of doping and temperature. Simulations show detectivity > 10 11 Jones at 77 K for Hg 0.78Cd 0.22Te.
