Tunable moiré bands and strong correlations in small-twist-angle bilayer graphene
Tunable moiré bands and strong correlations in small-twist-angle bilayer graphene
According to electronic structure theory, bilayer graphene is expected to have anomalous electronic properties when it has long-period moir\'e patterns produced by small misalignments between its individual layer honeycomb lattices. We have realized bilayer graphene moir\'e crystals with accurately controlled twist angles smaller than 1 degree and studied their properties …
