    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.

    The spectra were obtained from a partially oxidized nickel surface and were fitted with the software AAnalyzer(R). The two components at lower binding energy (displayed in olive green) are associated with Ni2O3, the component at higher binding energy (displayed in purple) is associated with adventitious oxygen. Data included in a Master Thesis (Guzmán-Bucio, Dulce M. Mecanismo de oxidación de níquel metálico, Cinvestav, Querétaro).

    Fitting of intrinsic O 1s signals for different photon energies (6736.5, 6836.5, 6936.5, 7387.5, 7487.5, and 7587.5 eV). The original spectra were analyzed under the Active background approach. The intrinsic signals were then obtained by modeling the extrinsic inelastic background accounting for the finite thickness (18 nm) of the oxide layer and X-ray extinction with a modified version of the method proposed by Herrera-Gomez Alberto, The photoemission background signal due to inelastic scattering in conformal thin layers, Queretaro, 2023.

    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.

    Fitting of intrinsic Fe 2p signals for different photon energies (from top to botton 6836.5, 6736.5, 7587.5, and 7387.5 eV). The original spectra were analyzed under the Active background approach. The intrinsic signals were then obtained by modeling the extrinsic inelastic background accounting for the finite thickness (18 nm) of the oxide layer, a semi-infinite metal layer and X-ray extinction with a modified version of the method proposed by Herrera-Gomez Alberto, The photoemission background signal due to inelastic scattering in conformal thin layers, Queretaro, 2023.

    C 1s spectra was obtained from the surface of a nickel thick sample that was exposed to ultra pure oxygen at 100°C for 8 minutes in the tubular furnace. The peaks at 284.56, 286.50, and 288.15 eV correspond to C-C, C-O, and C=O bonds, all present in adventitious carbon. The peak at 292.62 eV probably is associated to compounds with C-C, C-O and C-H bonds or physisorbed CO2. Finally, the peak at 282.98 eV is diffused carbon, respectively.
