摘要：

The present paper analyzes the harge transport mechanisms and spectrometric properties of In/CdTe/MoOx heterojunctions prepared by magnetron sputtering of indium and molybdenum oxide thin films onto semi-insulating p-type single-crystal CdTe semiconductor, produced by Acrorad Co. Ltd. Current-voltage characteristics of the detectors at different temperatures were investigated. The charge transport mechanisms in the heterostructures under investigation were determined: the generation-recombination in the space charge region (SCR) at relatively low voltages and the space charge limited currents at high voltages. The spectra of Cs-137 and Am-241 isotopes taken at different applied bias voltages are presented. It is shown that the In/CdTe/MoOx structures can be used as X/gamma-ray detectors in the spectrometric mode.
