The Electronic Properties of Quasi-One-Dimensional TiS<sub>3</sub> and ZrS<sub>3</sub>

ORAL

Abstract

The transition metal trichalcogenides (TMTs) are an emerging class of 2D materials in which 2D sheets are formed by the van der Waals-like bonding of quasi-1D chains. Here we present our work on the electronic properties of two TMTs, TiS3 and ZrS3, including the experimental band structure from nanospot angle resolved photoemission spectroscopy (nanoARPES). The band structures of both TMTs exhibit strong in-plane anisotropy due to their quasi-1D structure. The extracted effective hole mass for both materials is doubled along the chain direction, giving rise to a preferential charge transport direction. Additionally, high resolution nanoARPES measurements show a spin-orbit coupling splitting at the top of the valence band in TiS3. This spin-orbit coupling splitting is expected to increase for heavier TMTs such as ZrS3 and could be utilized to produce a spin polarized surface current.
