我们研究了正常/铁磁/正常硅烯结中的谷分辨和自旋分辨热电输运。由于谷和自旋自由度之间的耦合,可以证明热诱导的纯谷流和自旋流。这些电流的大小和符号可以通过调节铁磁交换场和局部外电场来控制,从而实现电流的可控性。我们还发现了完全谷极化和/或自旋极化的电流。与电流类似,由于能带结构的对称性,产生了具有零电荷对应物的可调纯自旋和/或谷型热电偶。这些结果表明,在硅烯中产生纯谷(自旋)电流和热电势是一种可行的方法。
We have investigated the valley and spin resolved thermoelectric transport in a normal/ferromagnetic/normal silicene junction. Due to the coupling between the valley and spin degrees of freedom, thermally induced pure valley and spin currents can be demonstrated. The magnitude and sign of these currents can be manipulated by adjusting the ferromagnetic exchange field and local external electric field, thus the currents are controllable. We also find fully valley and/or spin polarized currents. Similar to the currents, owing to the band structure symmetry, tunable pure spin and/or valley thermopowers with zero charge counterpart are generated. The results obtained here suggest a feasible way of generating a pure valley (spin) current and thermopower in silicene.
