The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.

W4f region has well-separated spin-orbit components (Δ metel =2.17eV). Loss feature for W metal appears at 37eV and 42eV for WO 3. W metal loss feature overlaps WO 3 4f peaks. Peaks in the W4f region have an asymmetric peak shape for tungsten metal. Tungsten compounds, such as the oxide, have symmetric W4f peaks.
