The results of an experimental investigation of the photoconductivity
of n- and p-CdxHg1-xTe X (x=0.2-0.3) deposited on the surface of alumi
num thin films are presented. The results obtained are analyzed with a
llowance for the influence of the surface space-charge region and the
recombination process in it. The values of the rate of surface recombi
nation and the surface mobility of the charge carriers are determined
from measurements of the photoconductivity and the barrier photocurren
