Berry Curvature Induced Valley Hall Effect in Non‐Encapsulated hBN/Bilayer Graphene Heterostructure Aligned with Near‐Zero Twist Angle
Abstract Valley Hall effect is observed in asymmetric single‐layer and bilayer graphene systems. In single‐layer graphene systems, asymmetry is introduced by aligning graphene with hexagonal boron nitride (hBN) with a near‐zero twist angle, breaking the sub‐lattice symmetry. Although a similar appro...
