## Description

- description: In the twisted trilayer graphene (tTLG) platform, the rich beating
    patterns between the three graphene layers give rise to a plethora of new length
    scales and reconstructed electronic bands arising from the emergent moiré and
    moiré-of-moiré superlattices. The coexisting lattices and superlattices interact
    and compete with each other to determine the overall transport properties of tTLG,
    the hierarchy of which can be electrostatically controlled by tuning the out-of-plane
    charge distribution or layer polarization. In this work, we measure the stability
    diagram of layer-polarized quantum Hall states in tTLG by systematically mapping
    out layer-specific Chern numbers in each layer and intra- and interlayer Chern
    transitions as a function of displacement field D and total carrier density n.
    In contrast to twisted bilayer systems, the rich interplay between the three atomic
    layers gives rise to a complex layer-polarized stability diagram with unconventional
    transport features that evolve rapidly with electric and magnetic fields. The
    stability diagram quantitatively characterizes the interlayer screening and charge
    distribution in tTLG with implication of strong interatomic-layer Coulomb coupling.
    Our work provides comprehensive guidance and insights into predicting and controlling
    layer-polarization and interlayer transitions in tTLG, and for tuning the individual
    role and interactions of each participating constituent toward novel material
    properties.
