Correlated Insulator Behaviour at Half-Filling in Magic Angle Graphene Superlattices
Yuan Cao, Valla Fatemi, Ahmet Demir +9
Van der Waals (vdW) heterostructures are an emergent class of metamaterials comprised of vertically stacked two-dimensional (2D) building blocks, which provide us with a vast tool…
