XPS Peak Fitting
The high-resolution XPS spectra were fit with a Shirley background. A mixed GaussianLorentzian function was used to describe the peak shape. The Si 2p lines for silicon dioxide
were fit with line-shape of GL(10), while C 1s, O 1s and N 1s were better fit with GL(30). In
curve fitting of C 1s and N 1s, components were allowed to have full widths at half maximum
(FWHM) in the range of 1.9-2.2 eV. Additionally, the position in binding energy and FWHM
of specific components were constrained to have ± 0.3 eV and ± 0.2 eV the same value,
respectively.
