    The background was modeled with a Tougaard background (calculated with a NiO-specific energy loss function) and a Narrow-Shirley background correlated for the main and satellite features, Sample was processed at the Nanofilm Processing and Characterization Laboratory, Cinvestav-Queretaro, Mexico. Ni was sublimated on a silicon substrate at high vaccum and then transferred into a tubular furnace for the oxidation

    The spectra were obtained from the surface of a metallic nickel thick sample exposed to UHP O2 at 300°C for 20 min in a tubular furnace. The six doublets are associated to NiO.

    The spectra were obtained from the surface of a metallic nickel thick sample exposed to UHP O2 at 100°C for 8 min in a tubular furnace. The spectra were fitted through the block approach* and are displayed normalized. The main peak (shown in olive green) corresponds to the metallic component; the five doublets are associated to the oxide components. Data included in a Master Degree Thesis (Guzmán-Bucio et al. "Oxidation mechanism of metallic nickel," to be published). * A. Herrera-Gómez, F.S. Aguirre-Tostado, Y. Sun, P. Pianetta, Z. Yu, D. Marshall, R. Droopad, W.E.

    The main doublet was fitted with three symetric Voigt doublets (shown in navy blue, blue and aqua). The spectra was obtained from the surface of a metallic nickel thick sample deposited by thermal sublimation in UHV conditions. Data included in a Master Degree Thesis (Guzmán-Bucio et al.
