The influence of lattice termination on the edge states of the quantum spin Hall insulator monolayer 1T'-WTe_2
Abstract
We study the influence of sample termination on the electronic properties of the novel quantum spin Hall insulator monolayer 1T'-WTe2. For this purpose, we construct an accurate, minimal 4-orbital tight-binding model with spin-orbit coupling by employing a combination of density-functional theory calculations, symmetry considerations, and fitting to experimental data. Based on this model, we compute energy bands and 2-terminal conductance spectra for various ribbon geometries with different terminations, with and without magnetic field.\n\nThe provided repository contains all code and data to reproduce the results of this study.
