Fig. 1: Genuine vs scaled graphene lattice hosting a superlattice potential.
From: Electrostatic superlattices on scaled graphene lattices
a Schematic of a two-terminal graphene device of length L and width W in the presence of a superlattice potential of periodicity λ within the scattering region only, but not in the attached two leads. The red box is magnified in the surface plot shown at the right to indicate the smoothing of the superlattice potential. The white box is magnified in (b) for a genuine graphene lattice of site spacing a0 equal to the carbon–carbon bond length and (c) for a scaled graphene lattice of site spacing a given by a0 up-scaled by a factor s.
