Abstract
Niobium oxide (NbOx) films were deposited by pulsed dc magnetron sputtering at different total gas pressures and oxygen flow rates. Various film properties were characterized by X-ray photoelectron spectroscopy, atomic force microscopy, variable angle spectroscopic ellipsometry and four point probe. It was found that oxygen flow rates required for preparing NbO, NbO2 and Nb2O5 at a constant total pressure of 0.93 Pa were approximately 2, 4 and > 6 sccm, respectively. The results showed that the film properties, specifically composition can be significantly changed by the total gas pressure and the oxygen flow rate.
