Paper Abstract

Thin vanadium oxide coatings were made by vacuum evaporation followed by annealing posttreatment in the presence of air. The thickness increased by a factor as large as 2.3 upon oxidation. Temperaturedependent electrical conductivity as well as spectral transmittance were measured vs. annealing time; it took a few hours to establish V02 with well-defined semiconductor-metal transition at 57°C. Electron diffractograms indicated a bcc monoclinic transformation upon annealing, and electron micrographs showed pronounced grain growth. Initial XPS core level spectra gave evidence for vanadium in different oxidation states.
