Analysis of ion dynamics on Na2NbZnP3O12 glass using anomalous relaxation function.

Ion conducting Na2NbZnP3O12 glass is investigated for the mechanism of the ion dynamics and non-Debye relaxation. The impedance spectroscopic data of the sample is taken for a frequency range of 100Hz to 1MHz for a temperature range of 393K to 513K. Anomalous relaxation function is used to study the microscopic mechanism of ion dynamics through the complex relaxation time. The physical picture of the ion dynamics have studied with the trapped and hopping charge carriers. The many particle displacement function and its scaling are used to understand the length scale of ion dynamics. [ABSTRACT FROM AUTHOR]
