Ion dynamics in glassy ionic conductors: Scaling of mean square displacement of mobile ions

In this letter, we present for the first time a new scaling for the mean square displacement of mobile ions in glasses. We have obtained time-dependent mean square displacement of mobile ions by mapping the frequency-dependent conductivity into time domain. We have obtained a universal scaling for t...

Description
Summary:In this letter, we present for the first time a new scaling for the mean square displacement of mobile ions in glasses. We have obtained time-dependent mean square displacement of mobile ions by mapping the frequency-dependent conductivity into time domain. We have obtained a universal scaling for the mean square displacement of mobile ions for silver phosphate glasses. The present scaling for the mean square displacement is consistent with the scaling of the conductivity spectra and is supported by the structural features.
