ABSTRACT:
A materials system comprising a glass containing alkali metal ions capable of migrating and a silica, alumina, or tantala film deposited on the glass surface, the glass also containing high field strength ions that can change coordination. The direction of alkali metal ion flow depends on the film selected and the glass composition.
