Abstract

Abstract : In article number 2007503, Zhenyu Wang, Jianfeng Wang, Chaoyu Chen, and co‐workers develop a practical strategy to construct moiré Dirac cones around the Brillouin zone center by folding graphene Dirac cones in monolayer In2 Se3 /bilayer graphene heterostructures. The Fermi velocity of the moiré Dirac cones is reduced by ≈23%, and the reshaped Dirac point at the Γ point is elongated. Both features further confirm moiré Dirac fermion renormalization and interactions.
