Figure 1.

Unit cell of graphene-hBN structures with increasing superlattice period ${\ell }_{\mathrm{p}}$. All ribbons have nominal width of 5 nm and thickness of 0.33 nm. Gray spheres represent carbon atoms, pink spheres are boron atoms and blue spheres are nitrogen atoms. First Brillouin zone and corresponding high-symmetry points are also shown in the top-right panel.
