Two possible edge configurations for ZGNRs supercell, (a,b) represents configurations corresponding to even Nz-ZGNRs, while (c,d) corresponds to odd Nz-ZGNRs. Blue and green spheres represent carbon and oxygen atoms, respectively. Note: In both configurations, the bottom edge remains the same, only the relative arrangement of atoms on the top edge is different.
