Band structure for the left electrode, transmission spectrum, and band structure for the right electrode for model 6-ZGeNR in AP configuration: (a) and (b) are for 0.5 and −0.5 V, respectively. (c), (d), (e), and (f) refer to the transmission pathways at 0.24 eV for spin-up state at −0.5 V, spin-down state at −0.5 V, spin-up state at 0.5 V, and spin-down state at 0.5 V, respectively. The horizontal dotted lines indicate the chemical potentials of the left and right electrodes. The Fermi level is set to zero.
