摘要
横向自旋阀是目前最重要的一种自旋器件。本文综述石墨烯作为横向自旋阀沟道材料的研究进展。虽然石墨烯作为横向自旋阀沟道材料的研究的报道已经很多,但是对于其电阻率、自旋寿命、自旋扩散长度、自旋霍尔角、自旋信号以及与其他材料的接触电阻等参数的确定仍有问题。目前实验获得的这些数据差别较大,影响因素尚不清晰。另外理论工作相对缺乏。这些问题将影响石墨烯在自旋电子学中的应用,需要进一步深入研究。
The lateral spin valve is the most important spintronic device studied in-depth so far. This paper reviews the research progress of graphene as the channel material of lateral spin valve. Although there are a lot of reports about the graphene as the channel material of lateral spin valve, the resistivity, the spin lifetime, the spin diffusion length, the spin Hall angle, the spin signal, and the contact resistance with other materials are not determinable. There exist greater differences between the data obtained by experiments, and the influence factors are unclear. In addition, it is relatively lack of theoretical work. These problems will affect the application of graphene in spintronics, so it is necessary to do further in-depth study.
