摘要

本文通过非平衡格林函数形式，研究了由于原子缺失(我们称之为“切割”)而导致结构突变时之字形石墨烯纳米带(ZGNR)的边缘输运。有趣的结果是，由于“切割”的宽度不同，结果明显不同。对于ZGNR，根据“切割”的宽度，电子可以在器件散射区完全透射(T = 1)或完全阻挡(T = 0)。

Quantum Transport of Edge States in Zigzag Graphene NanoRibbon in the Presence of an Abrupt Structure Change due to Missing Atoms

In this article, the edge transport of Zigzag Graphene NanoRibbon (ZGNR) in the presence of an abrupt structure change due to missing atoms, which we define as ‘cut’ is studied through Non-Equilibrium Green’s Function formalism. Interesting results are found that are notably different for difference in the width of the ‘cut’. For ZGNR, depending on the width of the ‘cut’, the electrons can be fully transmitted (T = 1) or fully blocked (T = 0) in the device scattering region.
