Researchers produce large regions of uniform rhombohedral four-layer graphene by introducing a small twist between two layers of bilayer graphene. Four-layer rhombohedral graphene is a new platform for realizing flat-band-based quantum phenomena in a natural way.

Researchers develop a groundbreaking method, Moiré metrology, to map the interaction of ultrathin layers. Information about the layers' interaction is imprinted on top of fine spatial patterns that emerge after the atomic relaxation.
