Signatures of van Hove Singularities Probed by the Supercurrent in a Graphene-hBN Superlattice

Author(s): D. I. Indolese, R. Delagrange, P. Makk, J. R. Wallbank, K. Wanatabe, T. Taniguchi, and C. SchönenbergerThe band structure of graphene can be strongly modified if its lattice is aligned with the one of a boron nitride substrate. A moiré superlattice forms, which manifests itself by the appearance of new Dirac points, accompanied by van Hove singularities. In this work, we present supercurrent measurem…[Phys. Rev.
