Abstract

There is an apparent contradiction between the predictions of Mott-theory and experimental conductivity data of vanadium phosphate glasses. In parallel investigations, measurements were made of the molar volume of V//20//5 glasses with 55, 60, 70, 75, and 85 mol % V//2O//5 systematically varying the vanadium valence state. It is demonstrated that phase separation is a characteristic feature of this glass system and that there is a compositional gradient at phase boundaries. It is suggested that amorphous V//2O//5// minus //x /0 less than x less than 1/ films prepared by chemical vapor deposition can be appropriate prototype materials for testing the predictions of polaron theory for conduction.
