The Influence of Electron Irradiation on the Dielectric Characteristics of Single Crystals of AgGaSe2

Resumo

The influence of various doses of electron irradiation on the dielectric permeability and specific conductance of ternary nonlinear optical crystals of AgGaSe₂ at various frequencies of the measuring field in a range of temperatures of 100–300 K is studied. It is found that the irradiation of single crystals leads to a decrease in the values of dielectric permeability and a significant increase in conductance. It is shown that dielectric permeability and conductance increase with the growth in temperature. It is found that the presence of several types of conductance is characteristic for the crystals of AgGaSe₂. Substantial frequency dispersion of the dielectric properties of the studied crystals is found.
