π共轭聚合物和单壁碳纳米管光物理的普适性

Universality in the Photophysics of pi-Conjugated Polymers and Single-Walled Carbon Nanotubes

Sumit Mazumdar, Zhendong Wang, Hongbo Zhao

摘要:

我们描述了π共轭聚合物和半导体单壁碳纳米管,因为它们在光激发下的行为显着的相似之处。这两类看似不同的材料之间的共同主题是π共轭,准一维性和强库仑相互作用。对这两个系统的理论理解需要超越传统的能带理论。我们提出了我们目前的理解的电子结构和激发态在一个共同的理论模型内的两个系统的配置。我们的目的是给出已经完成的实验的物理解释,并对未来的实验工作给予指导。

英文摘要:

We describe both pi-conjugated polymers and semiconducting single-walled carbon nanotubes because of the remarkable similarities in their behavior under photoexcitation. The common themes between these two seemingly different classes of materials are pi-conjugation, quasi one-dimensionality, and strong Coulomb interactions. Theoretical understanding of both systems requires going beyond traditional band theory. We present our current understanding of the electronic structures and excited state absorptions in both systems within a common theoretical model. Our aim is to give physical interpretations of experiments that have been performed and to give guidance to future experimental work.
