Features of manufacturing Cd1–xZnxTe ionizing radiation detector

Abstract

The article describes a newly-developed method of manufacturing of an operating element of the Cd_1–xZn_xTe-detector of ionizing radiation with high sensitivity to low-energy gamma radiation of the americium ²⁴¹Am radioactive isotope. The proposed two-step method of chemical surface treatment with the use of new bromine releasing polishing etchants significantly improves the quality of the detector material and increases its specific sensitivity to ionizing radiation. This allows to use smaller Cd_1–xZn_xTe plates, which results in lowering of the cost of detectors.
