We studied the oxidation of epitaxial Nb(110) films on a-plane sapphire substrates at elevated temperatures with x-ray scattering techniques. Comparing atmospheric versus dry oxidation, we observe a different behaviour resulting in the formation of chemically and structurally different oxides. Under
