One-Dimensional Spin Channel in Two-Dimensional Transition Metal Dichalcogenide Heterostructures

We show that it is possible to obtain one-dimensional (1D) spin channels at the lateral heterojunction of 2D transition metal dichalcogenides by a current flow without the necessity of any external magnetic field. This originates from the native spin orbit coupling of 2D materials in conjunction with the electric field that develops due to conduction band-offset at the junction. Nonetheless, we sh...
