Deskripsi
Magic-angle twisted bilayer graphene is interesting for its correlated superconducting and insulating states, but samples are typically micrometer-scale. Here, 3 × 5 mm2 twisted bilayer graphene samples are fabricated, exhibiting a flat band and large bandgap revealed by angle-resolved photoemission spectroscopy.
