    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.

    Fitting of the V 2p photoemission spectrum for a polycrystalline metallic surface, data were published by Lawson et al. (accession #0032402). The apparent asymmetry of the main photoemission line was modeled employing two symmetric Voigt doublets. Another three Voigt doublets were employed to optimize the fitting. The branching ratio of the five components was forced to be equal to the theoretically expected value (0.5165), which was taken from the Scofield tables.

    O 1s spectra was obtained from the surface of a hafnium oxide sample that was deposited by atomic layer deposition over Si(1 0 0) wafers. The component at ~530 eV is associated to Hf-O bonding in hafnium oxide. The component at 532 eV has contributions from the oxygen of the superficial hydroxil groups and from the oxygen in hafnium silicate at the interface HfO2/Si.

    Ru 3d metallic photoemission spectrum fitted. The data were published by Kaga et al. (accession #0041702). The film was deposited on a glass substrate by reactive sputtering. The spectrum was fitted with one Double-Lorentzian asymmetric doublet and two Voigt doublets. A signal from oxygen was detected in the sample, but the area is too small to be associated with any of the Ru 3d peaks and a Ru oxide (under the MultiLayer Method, considering the formation of a top ruthenium oxide layer, the composition of the oxide is RuO0.2), which strongly suggests that the three Ru 3d peaks are metallic components and that the oxygen signal is associated with an adventitious species. The branching ratio of the three doublets was forced to be equal to the theoretically expected value (0.6901), which was taken from the Scofield tables.

    Fitting of the Ge 3d photoemission spectrum for a single crystal surface, data were published by Lawson et al. (accession #0032903). The spectrum was fitted employing one Voigt doublet. The branching ratio was forced to be equal to the theoretically expected value (0.6865), which was taken from the Scofield tables.
