Vanadium Oxide Thin Films

Vanadium oxide thin films were deposited by reactive ion beam sputtering deposition onto glass substrates. The films were prepared by sputtering from a metallic vanadium target with an argon+oxygen ion beam in vacuum. Different processing conditions were evaluated with focus in obtaining monoclinic VO2(M) phase, which is known to exhibit a semiconducting-metal phase transition near room temperature. X-ray diffractometry (XRD) analyses revealed amorphous films for temperatures below 500°C. In crystalline films, the co-existence of VO2(M) with other phases was suppressed by pre-depositing a very thin metallic vanadium seeding layer which showed to promote the formation of single phase VO2(M) films. The VO2(M) films showed clearly the distinctive optical modulation behavior at the near-infrared range when going through the phase transition. The temperature dependence of sheet resistance supports the optical analyses revealing an evident semiconducting-metal behavior change up to over 2 orders of magnitude.

Vanadium Oxide Thin Films

W-doped Vanadium oxide thin films were prepared on the substrates of SiO2 glass, float glass and Si (100) by reactive magnetron sputtering after annealing in vacuum. The structure, morphology and phase transition were characterized by X-ray diffractometer, atomic force microscopy (AFM) and differential thermal analysis (DTA), respectively. The results show that, the major phase of W-doped films on SiO2 glass is VO2.Dopant reduce the phase transition temperature of VO2 thin films to 21.9°C. The root-mean-square roughness of the film increase for the longer deposition time.
