自旋量热电子器件对未来低功耗技术的发展非常重要。我们提出了一种新的基于锯齿形石墨烯纳米带(ZGNR)的自旋量热学器件,它是由单氢端的ZGNR(ZGNR-H)和双氢端的ZGNR(ZGNR-H2)组成的异质结。我们预测,在相反方向上流动的自旋上升和下降电流可以由温差而不是外加偏压引起。热自旋电流相当大,与石墨烯的前人工作相比有了很大的改善。此外,我们的研究还获得了热巨磁阻,可以用来制作高效的自旋热电子学磁阻器件。
Spin caloritronics devices are very important for future development of low-power-consumption technology. We propose a new spin caloritronics device based on zigzag graphene nanoribbon (ZGNR), which is a heterojunction consisting of single-hydrogen-terminated ZGNR (ZGNR-H) and double-hydrogen-terminated ZGNR (ZGNR-H2). We predict that spin-up and spin-down currents flowing in opposite directions can be induced by temperature difference instead of external electrical bias. The thermal spin-up current is considerably large and greatly improved compared with previous work in graphene. Moreover, the thermal colossal magnetoresistance is obtained in our research, which could be used to fabricate highly-efficient spin caloritronics MR devices.
