From: Origin of multiple band gap values in single width nanoribbons

Average of the local potentials of YZ atomic plane plotted in periodic direction of the supercell for (a) 5-ZGNRs and (b) 6-ZGNRs. Note: Switching of the deepest potential well and band gap values from config. II (Nz = 5) to config. I (Nz = 6).
