Description
Recent studies have proposed devices consisting of multiple graphene layers with near magic-angle twists as a promising platform for experimentally realizing correlated topological states. In such systems, moiré superlattices originating from consecutive layers are expected to experience lattice relaxation that significantly modifies the electronic band structure of the device.
Here we present our progress in characterizing structural and electronic properties of a twisted multilayer graphene device using scanning probe microscopy, that provide insight into how lattice relaxation modifies electronic band structure.
