Abstract

Radiation-thermal effects were studied in corundum single crystals exposed to an ionizing radiation. The laws of variation of the electrical properties of a target material under the action of these factors were established. In particular, it is established that the dose dependence of the electric conductivity of irradiated samples is described by a curve with extremum. The radiation-induced phenomena observed are explained within the framework of existing models. The temperature dependence of the dielectric loss tangent of irradiated samples changes in a complicated manner (in particular, a maximum appears in this curve). There are two temperature regions in which the loss tangent exhibits special features. The activation energies have been determined and a hypothesis about the nature of the observed dielectric absorption is formulated.
