The Impact of Adjusted Electric Field on The Electrical and Magnetic Properties of NiBr2 Monolayer with Density Functional Theory

Abstract

The density functional theory was employed to the non-collinear magnetic calculations to consider the impact of spin-orbit interactions and external electric field on the NiBr2 monolayer. It was shown that spin-orbit interaction reduces the energy gap at Γ point. It was also shown that the transition from an indirect semiconductor to a metal happens by applying an external electric field. Furthermore, we discovered spin splitting after combining the spin-orbit interaction and electric field. Our findings showed that the spin-orbit interaction and external electric field play important role in the NiBr2 monolayer, especially for designing spintronic devices.
