Strain-dependent one-dimensional confinement channels in twisted bilayer 1T'-WTe_2
arxiv(2024)
摘要
The low symmetry and anistropic lattice of 1T' WTe_2 is responsible for
the existence of parallel one-dimensional channels in the moiré patterns of
twisted bilayers. This gives the opportunity to explore moiré physics of a
different nature to that widely observed in twisted bilayers of materials with
hexagonal symmetries. Here, we combine plane-wave and linear-scaling density
functional theory calculations to describe the electronic properties of twisted
bilayer 1T' WTe_2. For a small change in the lattice parameters of the
constituent 1T' WTe_2 monolayers, we find a substantial moiré-induced
striped electrostatic potential landscape in the twisted bilayer, with a
peak-to-trough magnitude >200 meV.
