Abstract

The p⁺-v-n⁺ detectors applied in selective detection of nuclear radiation have been examined by the Light Beam Induced Current (LBIC) method. The LBIC method enables the comprehensive analysis of photocurrent generated by focused light beam in the microregion in active area of detector. Results of LBIC examinations allowed comparing two kinds of structures. One kind of the structures is those that fulfill requirements regarding parameters of diodes applied in the detection of nuclear radiation. For other kind, dark current exceeds the permissible value. The capacity-voltage characteristics have been presented too.
