边缘态

Fe原子链的吸附位置的不同，对边缘态的影响不同，导致的自旋极化的程度也不也一样。

Different adsorption-site of the Fe chain have different influence on the edge states of the nanoribbon , and the degree of spin-polarization are different .

我们发现吸附能不仅受GNRs边缘态的制约，也受石墨带的宽度和衬底取向的影响。

We found that the adsorption energy is constrained not only by the GNRs edge states , but also by the band width and the substrate orientation .

结果表明，结构因子和磁势垒都能改变电子散射模数，电子输运谱因此变得复杂而丰富，散射区域出现了完全局域态和磁边缘态。

The results show that the changes of both structural factors and magnetic field can affect the electronic scattering behavior and result in various patterns of electronic transmission .

锯齿状石墨烯纳米条带是半导体，费米能附近有两个能量简并的边缘电子态，分别被自旋向上通道和自旋向下通道所占据。

Zigzag edge graphene nano-ribbon is semiconductor with two degenerate electronic edge states near the Fermi level occupied by different spin channel each other .

吸附不同的原子链对石墨纳米带自旋输运的影响之所以不同的主要是通过对破坏其边缘磁距以及边缘态的对称性造成的影响不同。

Due to the effects on the magnetic moment and the edge states of the nanoribbon are different , and the adsorption of different atomic chain can engender different polarization .
