W-Doped Vanadium Oxide Thin Films Prepared by Reactive Magnetron Sputtering

Article Preview

Abstract:

W-doped Vanadium oxide thin films were prepared on the substrates of glass and Si (100) by reactive magnetron sputtering after annealing in vacuum. The structure and morphology were characterized by X-ray diffractometer and atomic force microscopy(AFM), respectively. The results show that,when the oxygen volume percent (Po2) increasing from 15% to 25%, the films on the Si(100) were vanadium oxides with high-valences. After vacuum annealing at 500°C for 2h, the major phase of W doped films on glass is VO2. The surface roughness of the film increase for the longer time annealing.
