Quantum blockade and loop currents in graphene with topological defects
... Graphene is a single layer of graphite with a honeycomb lattice consisting of two triangular sublattices. This peculiar structure of graphene gives rise to two linear “Dirac-type” energy dispersion spectra around two degenerate and inequivalent points K and K⬘ at the corner of the Brillouin zone.1,2 ...
