Abstract

Scaling was applied to a similar series of Na-germanate glasses. However, such a study extends to lower temperatures and to lower ion concentrations to include the unmodified GeO2 glass. Although good agreement was found with the findings of Roling and co-workers in that the ac conductivity of the modified glasses conform to scaling at temperature above ambient, the temperature results indicate that this scaling begins to fail for the lowest ion-containing samples. This paper demonstrates that this failure was not the result of any change in ion dynamics but rather was the direct result of the existence of two separate and distinct contributions to the NCL present in these materials.
