(a, b) Band structure for the left electrode (left panels), transmission curve (middle panels), and band structure for the right electrode (right panels) with AP configuration for 5-ZGeNR and 6-ZGeNR at zero bias, respectively. The Fermi level is set at zero. (c, d) Isosurface plots of wave functions of and subbands for spin-up states of 5-ZGeNR and 6-ZGeNR at the -point, respectively.
