## Description

- description: "Moiré effects in twisted or lattice-incommensurate vertical assemblies
    of two-dimensional crystals give rise to a new class of quantum materials with
    rich transport and optical phenomena, including correlated electron physics in
    flat bands of bilayer graphene and moiré excitons in semiconductor heterostructures.
    These phenomena arise from modulations of interlayer hybridization on the nanoscale
    of spatially varying atomic registries of moiré supercells. Due to finite elasticity,
    however, lattices of marginally-twisted homobilayers and heterostructures can
    transform from moiré to periodically reconstructed patterns with triangular or
    hexagonal tiling. Here, we expand the notion of nanoscale lattice reconstruction
    to the mesoscopic scale of extended samples and demonstrate rich consequences
    in optical studies of excitons in MoSe2-WSe2 heterostructures with parallel and
    antiparallel alignment. Our results provide a unified perspective on diverse and
    partly controversial signatures of moiré excitons in semiconductor heterostructures
    by identifying domains with exciton properties of distinct effective dimensionality
    and establish mesoscopic reconstruction as a compelling feature of real samples
    and devices with inherent finite-size effects and disorder. Generalized to stacks
    of other two-dimensional materials, this notion of mesoscale domain formation
    with emergent topological defects and percolation networks will instructively
    expand our understanding of fundamental electronic, optical, and magnetic properties
    of van der Waals heterostructures.\r\n"
