Is there a "native" band gap in ion conducting glasses?

TL;DR

This paper explores the hypothesis that ion conducting glasses have a band gap in their ion site energy spectrum, similar to semiconductors, affecting how ion conduction occurs.

Contribution

It proposes the concept of a band gap in ion site energies in glasses, drawing an analogy with semiconductor physics to explain ion conduction mechanisms.

Findings

Suggests a band gap exists in ion site energies in glasses

Proposes ion conduction occurs via vacancies and interstitial ions

Establishes an analogy between glasses and intrinsic semiconductors

Abstract

It is suggested that the spectrum of ion site energies in glasses exhibits a band gap, establishing an analogy between ion conducting glasses and intrinsic semiconductors. This implies that ion conduction in glasses takes place via vacancies and interstitial ions (as in crystals).
