Structural characterization of the ac conductivity in Ag ion conducting glasses

摘要: The material trends in various silver ion conducting glasses have been studied recently by focusing on the relationship between first sharp diffraction peak (FSDP) wave number Q, and fitting parameters of ac conductivity, precisely ratio (log A)/n, where A n represent pre-exponential factor power law exponent Jonscher’s law, respectively. In present paper, a model for FSDP dependence A)/n has proposed good agreement found with experiments. By using concept bond fluctuation superionic conductors, results successfully explained, leading to conclusion that universal aspect reflects pattern potential barrier at intermediate length scales. result reconfirms transport is intimately related number.
