我们提出了一种基于赝自旋的自旋阀，其中石墨烯双层相邻区域中的赝自旋极化由外部栅极控制。数值计算表明这种器件具有较大的开关比。这一发现为赝自旋电子学的实现提供了希望：一种基于赝自旋操纵的电子学形式，类似于自旋电子学应用中对物理自旋的控制。
We propose a nonmagnetic, pseudospin-based version of a spin valve, in which the pseudospin polarization in neighboring regions of a graphene bilayer is controlled by external gates. Numerical calculations demonstrate a large on-off ratio of such a device. This finding holds promise for the realization of pseudospintronics: a form of electronics based upon the manipulation of pseudospin analogous to the control of physical spin in spintronics applications.
