Electrical properties of Cu1−x Ag x GeAsSe3 (x = 0.55–0.65) at low temperatures and high pressures

Chalcogenides Cu_1-xAg_xGeAsSe₃ (x = 0.55–0.65) are synthesized, and their electrical properties are studied at temperatures of 78–400 K and pressures of 15–45 GPa. The compounds are found to be mixed electronic-ionic conductors. Increasing the fraction of silver lead to an increase conductivity and shifts the region of considerable change in electrical properties at high pressures toward even higher pressures.
