Metallic Ni 2p spectrum fitted only with symmetric Voigt lineshapes
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. "Oxidation mechanim of metallic nickel," to be published).

Partially oxidized Ni 2p spectrum fitted through the Block Approach
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.

Oxygen in hafnium oxide obtained by ALD
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.

Fitting of intrinsic signals from the O 1s core level from a partially oxidized sample
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.

Fitting of a Rh 3d photoemission spectrum (from metallic rodhium) with a Doniach-Sunjic lineshape
Fitting of the Rh 3d photoemission spectrum for the element (research grade), data were provided by Vincent Crist (The use of the spectrum requires acknowledging XPS library website, https://xpslibrary.com/, the data is copyrighted). In this approach, the main signal was fitted with a Doniach-Sujic peak and an additional Voigt peak was required to improve the fitting. The total background was modeled under the active background approach in which the extrinsic background was modeled with a Tougaard type background, while the intrinsic background was represented with a Narrow Shirley background and a set of symmetric peaks.

V 2p photoemission spectrum fitted with symmetric lineshapes
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.

Carbon in a nickel oxide sample
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.

Partially oxidized Ni 2p spectrum fitted through the Block Approach
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.
