Size Quantization of Dirac Fermions in Graphene

Caption

This graph shows electrical conductance, G, of electrons (black) and holes (red) in graphene nanoconstriction (shown in SEM image), as a function of electron/hole wave vector (momentum) showing characteristic steps (quantization of conductance) as indicated by arrows.
