Here ...C1s spectrum for contamination typically has C-C, C-O-C, and O-C=O components. The C-C component may be set to a binding energy of 284.8eV, by default. Not always a valid charge reference value (e.g., C1s peak for adventitious carbon on native oxide of aluminum appears at ~286eV).To improve the quantification of oxygen content in the deconvoluted C 1s spectra, Smith et al. proposed a method based on a 7-peak C 1s deconvolution (3 C–C peaks, 3 oxygenated peaks, and π-π∗ transition peak), which resulted in C:O ratios in good agreement of those obtained from total C 1s and O 1s spectra.
