Proximitized materials made of graphene and transition-metal dichalcogenides

Graphene on transition-metal dichalcogenides exhibits proximity spin-orbit
effects opening new venues for optospintronics, and provides route for
exploring robust helical edge states. Some of the transition-metal
dichalcogenides showing metal-insulator transition and the sequence of
different charge density wave transformations. In such a case a fascinating
finding is observed as the 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 suggest relevant orbital and spin-orbital proximity effects
by means of phenomenological symmetry-based Hamiltonians.

Minden érdeklődőt szeretettel várunk.
