Tunable atomically enhanced moiré Berry curvatures in twisted triple bilayer graphene
In consecutively twisted trialyer material platforms, the complex atomic landscape of coexisting moir\'e superlattices gives rise to rich electronic properties. Near band-insulator gaps of each moir\'e superlattices, the authors report here transport signatures of strong Berry curvatures in twisted triple bilayer graphene, enhanced by tunable inter-moir\'e lattice reconstruction. This work shed new insights in understanding the atomic and electronic properties of twisted multilayers, and paves a path towards engineering the band structure and its topology for designer material functionalities.
