WebSep 19, 2014 · The chiral d -wave superconducting state in graphene is a spin-singlet -wave state. Due to the sixfold symmetry of the honeycomb lattice, the two d -wave states carry an equal weight but have a relative π /2 phase shift. This results in a fully gapped bulk superconducting state at any finite doping level in graphene. Webaligned with the nodes of a d-wave superconducting gap was observed via STM in Refs. [32,33]. In addition to the symmetry of the gap, the spatial pro le of a YSR state may also provide information about the shape of the Fermi surface as was exempli ed for an s-wave su-perconductor in Ref.
