不纯石墨烯中光谱重排的数值模拟证据
Numerical simulation evidence of spectrum rearrangement in impure graphene
摘要：
通过数值模拟，我们证实，在石墨烯与点缺陷的准间隙打开附近的共振态的杂质浓度增加。我们证明，在这个quasigap的状态不能再描述的波矢量和强烈本地化。我们可视化的状态对应的状态密度的最大值内的quasigap，并表明它们产生的杂质对集群。
英文摘要：
By means of numerical simulation we confirm that in graphene with point defects a quasigap opens in the vicinity of the resonance state with increasing impurity concentration. We prove that states inside this quasigap cannot longer be described by a wavevector and are strongly localized. We visualize states corresponding to the density of states maxima within the quasigap and show that they are yielded by impurity pair clusters.
