Abstract:

The electrical resistivity of near-stoichiometric crystalline V2O5 was measured as a function of crystal orientation and oxygen partial pressure from 25C to 300C. Conductivity is insensitive to ambient atmosphere. The activation energy for conduction is 0.20 ev. Molten V2O5, however, is sensitive to oxygen partial pressure. Its conductivity is proportional to P-O2 to the -16th power. Anomalously high electrical resistivity was observed for glassy V2O5 films. Author
