多层石墨烯的普适光导性起源及光学堆叠序列识别

Origin of Universal Optical Conductivity and Optical Stacking Sequence Identification in Multilayer Graphene

Hongki Min, A. H. MacDonald

摘要:

我们表明,在正常的$N$层的石墨烯多层膜的通用光学电导率的起源是一个新兴的手征对称性,保证了$σ(ω)=Nσ_{uni}$在低和高的频率限制。[ $σ_{uni}=(π/2) e^2/h$ ].我们使用这种物理关系到中频电导率趋势的多层堆叠序列的定性特征。

英文摘要:

We show that the origin of the universal optical conductivity in a normal $N$-layer graphene multilayer is an emergent chiral symmetry which guarantees that $σ(ω)=Nσ_{uni}$ in both low and high frequency limits. [$σ_{uni}=(π/2) e^2/h$]. We use this physics to relate intermediate frequency conductivity trends to qualitative characteristics of the multilayer stacking sequence.
