Disorder in Ag7GeSe5I, a superionic conductor: temperature-dependent anharmonic structural study
{{output}}
A temperature-dependent structural investigation of the substituted argyrodite Ag(7)GeSe(5)I has been carried out on a single crystal from 15 to 475 K, in steps of 50 K, and correlated to its conductivity properties. The argyrodite crystallizes in a cubic cell... ...
