Photosensitive barrier structures were fabricated by high-power pulsed laser irradiation of a freshly-cleaved surface of n-type bulk Cd1-xZnxTe substrates. Their electrical properties were investigated and discussed. Dominant carrier mechanisms at a forward and a reverse bias in terms of a recombination and tunnel-recombination model were analyzed. At the illumination reaching 100 mW.cm(-2), these surface-barrier p-Cd1-xZnxTe/n-Cd1-xZnxTe structures were possessed by the following photoelectric parameters: open-circuit voltage V-oc = 0.61 V, short-circuit current I-sc = 0.21 mA and fill factor FF = 0.49, respectively.
