Abstract

The anisotropy in the form of quasi one-dimensional (1D) chains in transition metal trichalcogenides (TMTCs) makes them stand out compared to other more conventional two-dimensional (2D) materials. Here, we experimentally investigated the electrical properties of stripes of the TMTC ZrSe ₃, particularly in regard to their width and thickness. For this, we compared narrow samples with wider samples where both have a comparably similar length and thickness and found that the conductivity happens dominantly in the outer selenium atoms, i.e., across the chains, showcasing the in-plane electrical anisotropy of ZrSe ₃. Comparing stripes of different thicknesses shows a drastic increase in band gap energy from 0.37 eV up to 0.63 eV for thinner samples.
