## Description

- description: "Moiré structures formed by twisting three layers of graphene with
    two independent twist angles present an ideal platform for studying correlated
    quantum phenomena, as an infinite set of angle pairs is predicted to exhibit flat
    bands. Moreover, the two mutually incommensurate moiré patterns among the twisted
    trilayer graphene (TTG) can form highly tunable moiré quasicrystals. This enables
    us to extend correlated physics in periodic moiré crystals to quasiperiodic systems.
    However, direct local characterization of the structure of the moiré quasicrystals
    and of the resulting flat bands are still lacking, which is crucial to fundamental
    understanding and control of the correlated moiré physics. Here, we demonstrate
    the existence of flat bands in a series of TTGs with various twist angle pairs
    and show that the TTGs with different magic angle pairs are strikingly dissimilar
    in their atomic and electronic structures. The lattice relaxation and the interference
    between moiré patterns are highly dependent on the twist angles. Our direct spatial
    mappings, supported by theoretical calculations, reveal that the localization
    of the flat bands exhibits distinct symmetries in different regions of the moiré
    quasicrystals.\r\n"
