SUMMARY:Proximitized materials made of graphene and transition-metal dichalcogenides
DESCRIPTION:Martin Gmitra\nDepartment of Theoretical Physics and Astrophysics\nGraphene on transition-metal dichalcogenides exhibits proximity spin-orbit effects opening new venues for optospintronics [1], and provides route for exploring robust helical edge states [2, 3]. Some of the transition-metal dichalcogenides showing metal-insulator transition and the sequence of different charge density wave (CDW) transformations [4]. In such a case a fascinating finding is observed namely that induced proximity effects in graphene are significantly influenced by the presence of the commensurate charge density wave. We present our first-principles results for the electronic band structures and discuss relevant orbital and spin-orbital proximity effects by means of phenomenological symmetry-based Hamiltonians. \nThe work is supported by the VVGS-2019-1227. \n[1] M.
