Electrical properties of solid electrolytes with the general formula ABCD(3) (A = Ag, Cu; B = Pb, Sn; C = As, Sb; and D = S, Se)

摘要

The electrical properties of AgPbSbS3, AgSnAsS3, AgPbSbSe3, AgPbAsSe3, AgSnSbSe3, CuSnSbS3, CuSnSbSe3, CuSnAsSe3, AgSnSbS3, and AgPbASS(3) chalcogenides are studied by the method of impedance spectroscopy with the aim of searching for materials with improved properties (increased contribution of ionic transport, decreased temperatures of onset of ionic transport, increased conductivity, the presence of ferroelectric and magnetic properties, etc.). New ionic conductors and ferroelectric semiconductors are discovered.
