Twisted Bilayer Graphene
Twisted bilayer graphene forms a moiré superlattice due to the rotational misalignment between two graphene layers, resulting in characteristic periodic patterns.
As the scan size decreases from 200 nm to 5 nm, moiré patterns appear at larger scales and the atomic lattice is resolved at smaller scales.
