(Color online) Schematics of the molecular junction models has been displayed as a M1, b M2 and c M3, whose scattering region is flat, curved (U-shape) and double-curved (S-shape), respectively. The blue dashed rectangle in panel a donates the repeated unit cell of ZγGYNR, whose lattice constant is 12.297 Å. For clarity, the side-view in the scattering region for d M1, e M2 and f M3 corresponding to a–c have also been exhibited. L/R represents the left/right electrode
