First-principles study shows strain engineering alters Rashba spin splitting in 2D Janus WSeTe, indicating potential for low-power applications.
A research hotspot in recent years has been regulating the Rashba spin splitting under low-power operation.This study focuses on WSeTe due to its intrinsic structural asymmetry and strong spin-orbit coupling (SOC).. Herein, we have investigated the Rashba spin splitting in monolayer WSeTe based on first-principles DFT calculations.Our study reveals how strain-electric field manipulates the Rashba spin splitting, with strain playing a dominant role. Strain engineering can significantly enhance the Rashba
