▎ 摘 要
The proximity-induced spin-orbit coupling (SOC) in heterostructures of twisted graphene and topological insulators (TIs) Bi2Se3 and Bi2Te3 is investigated from first principles. To build commensurate supercells, we strain graphene and correct thus resulting band offsets by applying a transverse electric field. We then fit the low energy electronic spectrum to an effective Hamiltonian that comprises orbital and spin-orbit terms. For twist angles 0 degrees 0
