## Description

- description: The supermoiré lattice, built by stacking two moiré patterns, provides
    a platform for creating flat mini-bands and studying electron correlations. An
    ultimate challenge in assembling a graphene supermoiré lattice is in the deterministic
    control of its rotational alignment, which is made highly probabilistic due to
    the random nature of the edge chirality and crystal symmetry of each component
    layer. In this work, we present an experimental strategy to overcome this challenge
    and realize the controlled alignment of double-aligned hBN/graphene/hBN supermoiré
    lattice. Remarkably, we find that the crystallographic edge of neighboring graphite
    can be used to better guide the stacking alignment, as demonstrated by the controlled
    production of 20 moiré samples with an accuracy better than ~0.2º. Employing this
    technique, we are the first to fabricate the perfect double-aligned graphene supermoiré
    lattice and to observe the sharp resistivity peaks at band filling of 0, -4 and
    -8 electrons per moiré unit cell. Finally, we extend our technique to other strongly
    correlated electron systems, such as low-angle twisted bilayer graphene and ABC-stacked
    trilayer graphene, providing a strategy for flat-band engineering in these moiré
    materials.
