Electric properties of AgPbAsSe₃ at pressures up to 45 GPa

Abstract

The article is devoted to the investigation of electric properties of ferroelectric-semiconducting AgPbAsSe₃ at pressures up to 45 GPa and the existence of phase transitions in this compound. Our data show that there are two phase transitions at 1.5–2 and 31–32 GPa.
