Abstract In the present paper, we have theoretically investigated thermoelectric transport properties of armchair and zigzag graphene nanoribbons with Rashba spin–orbit interaction, as well as dephasing scattering processes by applying the nonequilibrium Green function method. Behaviors of electronic and thermal currents, as well as thermoelectric coefficients are studied. It is found that both electronic and thermal currents decrease, and thermoelectric properties been suppressed, with increasing strength of Rashba spin–orbit interaction. We have also studied spin split and spin density induced by Rashba spin–orbit interaction in the graphene nanoribbons.

具有 Rashba 自旋轨道相互作用的石墨烯纳米带的热电输运和自旋密度

摘要 在本文中,我们通过应用非平衡格林函数方法从理论上研究了扶手椅和锯齿形石墨烯纳米带与 Rashba 自旋轨道相互作用的热电输运性质,以及去相位散射过程。研究了电子和热电流的行为,以及热电系数。发现随着 Rashba 自旋轨道相互作用强度的增加,电子电流和热电流都降低了,并且热电特性受到了抑制。我们还研究了石墨烯纳米带中由 Rashba 自旋轨道相互作用引起的自旋分裂和自旋密度。
