Post "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. 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.
