Molybdenum oxide thin films with good adhesion and crystallinity were homogeneously deposited by the Chemical vapor transport of MoO3(OH)(2) and subsequent dehydration to the Mo oxide phase during hydrogen-reduction. This new deposition technique would be an effective deposition method for MoO3 thin films due to the simple, low-cost, large area deposition and eco-friendly process. The surface morphology dramatically changed by thermal annealing at different temperatures and a uniform similar to 1 mu m thickness was obtained. The effect of the annealing temperature is discussed.
