Edge channels of broken-symmetry quantum Hall states in graphene visualized by atomic force microscopy

Edge channels of broken-symmetry quantum Hall states in graphene visualized by atomic force microscopy

The broken-symmetry edge states that are the hallmark of the quantum Hall effect in graphene have eluded spatial measurements. Here, the authors spatially map the quantum Hall broken-symmetry edge states using atomic force microscopy and show a gapped ground state proceeding from the bulk through to...
