Manipulating the electronic and spintronic properties in PtS2/MoTe2 heterostructure with strain

Abstract

In this work, the strain engineering on the electronic and spintronic properties of PtS₂/MoTe₂ heterostructure is investigated by first-principle calculations. Based on the energy minimum principle, the most stable configuration of the PtS₂/MoTe₂ heterostructure is recognized. The mechanisms for the evolution of the band structures under different strains are analyzed by the atomic orbital projected band structures. Furthermore, a Rashba type spin texture of PtS₂/MoTe₂ heterostructure is predicted, with a formation mechanism revealed through atomic orbital projected spin textures. The strain tunable electronic and spintronic properties of PtS₂/MoTe₂ heterostructure hold great promise in applications of spintronics and nanoelectronics.
