Abstract

We have systematically investigated the structural property and electrical structures of the transition metal intercalated titanium disulfide compound Fe $_x$ TiS $_2$ ( $0\leq x\leq0.33$ ) from angle-resolved photoelectron spectroscopy with tunable polarized synchrotron radiation. The effect of intercalation on the energy bands and density of states of the host material around two high-symmetry points ( $\Gamma, L$ ) is studied. Charge transfer from the Fe atoms to the dichalcogenide layers leads to the movement of the Ti 3d-derived electron pocket. Two hybridized states are observed around $\sim500$ meV and Fermi level. Knowledge of hybridization among the Fe $3d$ , Ti $3d$ , and S $3p$ states is very important to understand the physical of Fe $_x$ TiS $_2$ system.
