## Description

- description: We report a twisted triple bilayer graphene platform consisting of
    three units of Bernal bilayer graphene consecutively twisted at 1.49∘ and 1.68∘.
    We demonstrate the atomic reconstruction between the two competing moiré superlattices
    strongly enhances the Berry curvature of each moiré band insulator state, characterized
    by measured strong nonlocal valley Hall effect that sensitively depends on the
    intermoiré competition strength, tunable by manipulating the out-of-plane carrier
    distribution. Our study sheds light on the microscopic mechanism of atomic and
    electronic reconstruction in twisted multilayer systems, by systematically investigating
    transport signatures of moiré Berry curvature and its enhancement from moiré-of-moiré
    lattice reconstruction. We show that the reconstructed electronic band can be
    versatilely tuned by electrostatics, providing an approach toward engineering
    the band structure and its topology for a quantum material platform with designer
    electrical and optical properties.
