Abstract

We investigate the effect of the twist angle on the proximity spin-orbit coupling (SOC) in graphene/NbSe2 heterostructures from first principles. The low-energy Dirac bands of several different commensurate twisted supercells are fitted to a model Hamiltonian, allowing us to study the twist-angle dependency of the SOC in detail. We predict that the magnitude of the Rashba SOC can triple, when ...
