▎ 摘　　要

Inspired by the bottom-up synthesis of nanoporous graphene (Moreno, C., Science, 2018, 360, 199), we investigate the magnetic and thermoelectric transport properties of nanoporous graphene nanoribbons (NP-GNRs) with different zigzag-edged configurations. Regardless of zigzag edges, a robust spin-semiconducting property is achieved, and the spin band gap shows a linear stark effect with a transverse electric field. The large spin Seebeck coefficient appears at a transition temperature from the ballistic resonant to tunneling regimes. When a temperature difference is applied across the device, the electrons or holes with different spin index flows at almost the same rate in the opposite direction were derived, and a perfect Seebeck effect is observed. These results presented here provide a useful insight for the real applications in carbon-based spin caloritronics.
