【Abstract】 Steady state characteristics of HgCdTe photovoltaic detectors are computed using a specially designed finite difference method. Reasonable results on carrier distributions, potential distributions and volt—ampere characteristics (including dark characteristics, characteristics under illumination and the effects of junction depth, substrate thickness and doping profile on the characteristic curves) are obtained. Problems in the computations are noted and future improvements are indicated.更多还原
