Thin films of amorphous transition metal oxides of Mo, W, V and Zn were prepared by pulsed laser deposition, and their optical properties and work function were determined. From the gradient of the absorption edge, Urbach energy was obtained, evaluating disorder in the semiconductor material. The work function of each material was obtained by Kelvin probe, and a slight correlation with Urbach energy was found. X-ray photoelectron spectroscopy indicated successful stochiometric transfer mainly for the lowest pressure and highest temperature samples.
