In the experiments, the stacking of other layers can be stacked layer by layer by using the method of direct growth, such as chemical bath deposition [17] and chemical vapor deposition [18]. To date, many vertical stacking structures based on graphene have been explored, such as graphene/Janus 2H-VSeTe [19], graphene/Janus 2H-VSeX (X = S, Te) [20], graphene/WTe2, etc. Scientists have done a lot of research on heterostructures, from the aspects of spin-orbital coupling [21], strains, applied electric field and Lattice mismatch, etc.
