Experimental and theoretical studies of the electronic structure of TiS2

Sulfur $K$- and titanium $L_{2,3}$-edge absorption spectra of transition-metal disulfide, Ti${\mathrm{S}}_2$, were measured using x-ray-absorption spectroscopy (XAS) and electron-energy-loss spectroscopy (EELS), respectively. All features in the experimental spectra are very well reproduced by full multiple-scattering-theory calculations. Combined analysis of theoretical and experimental XAS and EELS spectra, and linear muffin-tin orbital band-structure calculations, tend to demonstrate that Ti${\mathrm{S}}_2$ is a semimetal.
