Vanadium pentoxide thin films by XPS

Vanadium pentoxide thin films were grown on Al2O3 substrates by chemical vapor deposition and on glass substrates by plasma-enhanced chemical vapor deposition. While the films deposited on Al2O3 are polycrystalline, those grown on glass substrates show a strong (001) preferential orientation and are nanostructured. X-ray photoelectron spectroscopy measurements of the principal core levels for the surface of V2O5 films are reported.
