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.

Metallic Ni 2p spectrum fitted with double-Lorentzian lineshape
The main photoemission line (displayed in blue) was fitted with a Double-Lorentzian lineshape. 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 mechanism of metallic nickel," to be published).
