Simple computer model of a IR-photoconductor

摘要

The one-dimensional model of an IR photoconductor (PC) is developed for computer simulation. PC made from Hg_(1-x)Cd_xTe (MCT) consists of the contact section 1, the active IR irradiated section 2 and the contact section 3. One can change the length of every section, its composition, the density of majority carriers in it and the recombination velocities of minority carriers at both contacts. The model allows to find the distribution of minority carriers on PC length and the dependence of voltage responsivity on electric field, applied to PC.
