Probing Dirac Fermions in Graphene by Scanning Tunneling Probes
... Figure 4: Comparison between the topography of two areas 100nm x 100nm of (a) graphene
on SiO2 and (b) graphene on BN . (c) Comparison between two line cuts across (a),(b).
where, Ac is the unit cell area of graphene lattice.
The DOS in graphene differs qualitatively from that in non-relativistic 2D ...
