Abstract: Though of tremendous interest, graphene-based Moiré superlattices are still partially maintained as a mystery owing to the challenge of ab initio electronic structure calculations. This talk introduces the theory of angle-resolved photoemission spectroscopy (ARPES) experiments on 2D systems, calculates the ARPES pictures of graphene and graphene-based Moiré superlattices including single-layer graphene on hexagonal boron nitrides (hBN) and twisted bilayer graphene (TBG), reveals the physics behind them and shows what an ARPES experiment can tell about parameters of Moiré superlattices. Some other interesting research topics mainly regarding transport properties of Moiré multilayer systems are also briefly proposed.
