Electrically and mechanically tunable Rashba splitting in SbSeI Janus layer: a density functional theory study.

ABSTRACT: Two-dimensional materials with Rashba-like spin splitting near the Fermi level hold significant potential for next-generation spintronic devices. Using density functional theory based calculations, we demonstrate that spin-orbit coupling along with broken out-of-plane mirror symmetry induces strong Rashba splitting in the lowest conduction states of SbSeI Janus layer. This allows the possibility of spin control via an external electric field. The Rashba spin split bands are isotropic around the Γ point due to the presence of three-fold rotational [Formula: see text] symmetry. The values of Rashba splitting characteristics, namely Rashba energy [Formula: see text], crystal momentum offset [Formula: see text], and Rashba parameter [Formula: see text], are found to be 39.3 meV, 0.05 Å[Formula
