Crystal growth, characterization and electronic band structure of TiSeS

Layered semimetallic van der Waals material $\mathrm{Ti}{\mathrm{Se}}_{2}$ has attracted a lot of attention because interplay charge density wave (CDW) state and superconductivity. Its sister compound ${\mathrm{TiS}}_{2}$, being isovalent to having the same crystal structure, shows semiconducting behavior. The natural question rises---what happens at transition point in $\mathrm{Ti}{\mathrm{Se}}_{2\ensuremath{-}x}{\mathrm{S}}_{x}$, which is expected for x close one. Here we report growth characterization TiSeS single crystals study electronic structure using functional theory (DFT) angle-resolved photoemission (ARPES). We show that have morphology as $\mathrm{Ti}{\mathrm{Se}}_{2}$. Transport measurements reveal metallic state; no evidence CDW was found. DFT calculations suggest band similar $\mathrm{Ti}{\mathrm{Se}}_{2}$, but electron hole pockets are much smaller. ARPES results good agreement with calculations.
