Radiation effects in MCT A. V. Voitsekhovskii, A. P. Kokhanenko, A. G. Korotaev, D. V. Grigor’ev TSU, 36 Lenin av., Tomsk, 634050, Russia E-mail: vav@elefot.tsu.ru N. A. Kulchitsky, A. A. Melnikov MIREA, 78 Vernadsky av., Moscow, 119454, Russia E-mail: n.kulchitsky@gmail.com The review of influence various kinds of irradiation on properties of mercury cadmium tellurides solid solutions (MC) is made. <...> It is shown that the material practically does not lose the qualities at 1, 2012 the irradiation electron fluences up to 1017 cm–2 and gamma-irradiation doses up to 106 R. Formation mechanisms of electrically active radiation-induced defects (RD) and process of their evolution proceed identicall both in epitaxial films, and in bulk material of MCT. <...> Observable differences of results of irradiation on MBE MCT epitaxial films with variable composition and bulk material are caused mainly by different dynamics of accumulation of the electrical active RDs and dependence of electrophysical properties of a material on MCT composition. <...> Рассмотрено влияние различных видов облучения на свойства твердых растворов тел-луридов кадмия и ртути. <...> Показано, что данный материал практически не теряет своих качеств при облучении потоками электронов до 1017 см2 и гамма-квантами дозами до 106 Р. <...>
