An Xps Study of Solid Solutions Mo1–XNbxS2 (0 < x < 0.15)

详细

Solid solutions Mo_1–xNb_xS₂ (x = 0, 0.05, 0.10, and 0.15) crystallizing in the hexagonal structure 2H-MoS₂ are synthesized. The samples are characterized by powder X-ray diffraction (XRD) and Raman spectroscopies, X-ray photoelectron spectroscopy (XPS), and quantum chemical calculations (DFT). The changes occurring in the electronic properties of high-resistivity semiconductor MoS₂ and indicating metallic behavior of obtained solid solutions Mo_1–xNb_xS₂ are not accompanied by substantial changes in the atomic photoelectron spectra.
