Abstract: Tungsten diselenide (WSe<subscript>2</subscript>) was analyzed using x-ray photoelectron spectroscopy. A freshly exfoliated, oxygen-free flake was analyzed. Spectral regions for O 1s, W 4d, W 4f, W 5p, Se 3d and an extended region encompassing Se 3p, Se 3s, W 4d, Se LMM, and C 1s were acquired along with the valence band. Bulk quantitative analyses by x-ray fluorescence and x-ray diffraction indicated the material was stoichiometric and phase pure, respectively. [ABSTRACT FROM AUTHOR]
