Abstract

Molybdenum disulfide, a two-dimensional transition metal dichalcogenide, was analyzed using in situ x-ray photoelectron spectroscopy (XPS). The XPS spectra obtained from a fresh surface which was exfoliated and annealed in ultrahigh vacuum include a survey scan, high resolution spectra of O 1s, C 1s, Mo 3d, S 2s, S 2p, Mo 3p, Mo 4p, S 3s, and the valence band. Quantitative analysis indicates a sulfur deficient surface composition of MoS1.8, and impurities were below the XPS detection limit.
