Electrical Conduction in Relation to Local and Intermediate Range Structure of Rubidium Germanate Glasses
Published online by Cambridge University Press: 10 February 2011
Abstract
The dependence of dc electrical conductivity of a series of rubidium germanate glasses on rubidium oxide concentration is correlated with the structural information obtained from extended x-ray absorption fine structure analysis, density, x-ray photoelectron, Raman and far infrared absorption spectroscopy. Previously macroscopic molar or excess volume showed the most obvious correlation with the activation energy of conductivity. The present results demonstrate additional importance of the intermediate range structure.
