半无限扶手椅型边缘石墨烯不存在边缘态的严格证明
A rigorous proof of non-existence of edge state in the semi-infinite armchair edged graphene
摘要:
利用转移矩阵方法,给出了半无限扶手椅型边缘石墨烯中边缘态存在的条件。我们分别讨论了零能和非零能边缘态,并严格地分析了模型中边缘态的不存在性。
英文摘要:
With the help of transfer matrix method, the conditions for the existence of the edge states in the semi-infinite armchair edged graphene is given. We discuss zero-energy and non-zero-energy edge states separately, and show the nonexistence of the edge states in the model analytically and rigorously.
