The tunable anisotropic Rashba spin–orbit coupling effect in Pb-adsorbed Janus monolayer WSeTe
Can Yang, Jia Li, Xiaoli Liu, Congling Bai
Abstract
perturbation theory that Pb atom adsorption reduces the initial symmetry of the 2H-WSeTe monolayer and induces a strong spin-orbit coupling effect, so as to induce the anisotropic Rashba effect. Furthermore, the tunability of Rashba splitting was demonstrated by varying the adsorption concentration, adjusting the adsorption distance, and applying biaxial strain. This predicted adsorption system has potential value in spintronic devices.
