摘要：
Core level spectra, generated by monochromatic Al K alpha x-rays for a commercial, powdered tungsten disulfide (WS2) specimen, have been recorded and presented. The x-ray photoelectron spectra of WS2 obtained include a survey scan, high-resolution spectra of W 4f, S 2p, S 2s, W 4d, W 4p, O 1s, W 4s, S LMM, and the valence band. Quantitative analysis has been achieved using a two-parameter Tougaard background and line shapes indicated for fitting; using these methods a surface composition of WS2 is found.
