Abstract:

The chalcogenides Cu1 - x Ag (x) GeAsSe3 (x = 0.5, 0.8, 0.9) have been synthesized and their electrical properties have been studied at low temperatures. Compounds of this type are electron-ionic conductors with a mixed character of conduction. It has been shown that the substitution of copper atoms for a part of silver atoms in the AgGeAsSe3 compound leads to a decrease in the total conductivity, a decrease in the fraction of ionic component of the conductivity, a significant increase in the polarization times, an increase in the temperature of the onset of a noticeable contribution (as compared to the electron contribution) of the ionic transport, and a decrease in the activation energy of carriers.
