Abstract
Amorphous titania thin films were deposited by an off-plane filtered cathodic vacuum arc (FCVA) at a process pressure of 3.0×10-4Torr at room temperature. Core level of Ti 2p3/2(458.3eV) and O 1s (529.9eV) obtained from XPS spectrum and their deviation in binding energy (ΔBE=71.6eV) indicate that only the Ti4+of Ti oxidation state exists in the film and the film was of ideal stoichiometry. The film exhibits good optical properties, such as high transmittance and optical band gap. Moreover, it possesses bulk-like refractive index (up to 2.57 at 550nm) and lower extinction coefficient (∼10-4at 550nm) with smooth surface.
