Manifestation of site energy landscapes for ion transport in borate glasses

Abstract

The potential energy landscape of lithium borate glass of composition Li3B7O12 has been investigated by the charge attachment induced transport (CAIT) technique. Here, native Lithium ions have been replaced by...

Energy landscapes in alkali aluminum germanium phosphate glasses as probed by alkali proton substitution

“…As elaborated elsewhere, in this kind of unidirectional ion exchange, the effective diffusion coefficient for the foreign ion will always appear as concentration independent as long as D foreign ( D native,bulk . 32 This is a characteristic of the experiment. Since the goal of the experiment is to quantify only the native ion SED, no problem arises from this.…”
