Computational research based on the Density Functional Theory (DFT)
has been performed to explore the electronic structure of monolayer material
Transition Metal Dichalcogenides (TMDCs) Molybdenum Dichalcogenides MoXY (X;
Y = S; Se) in the first Brillouin zone by breaking its mirror symmetry due to the polarity
effect. Our study discovered that Rashba spin-splitting could be identified around the
? point by proposing the polarity effect on the system. Moreover, the anisotropic
characteristic of Rashba spin-splitting in this system can be explicitly analyzed by using
?
???? k p perturbation theory and the third-order symmetry group analysis. By performing
the spin textures analysis, this research also recognizes the in-plane direction of spin
textures. The tunable characteristic of the Rashba parameter of this monolayer polar
MoSSe system under the strain effects control exhibits its potential to be the candidate
of semiconductor material for the Spin Field Effect Transistor (SFET) device.
