在这篇文章中，我们综述了我们最近的理论工作的电子和光学性质的碳纳米管从背景到前景。金属碳纳米管的电子拉曼光谱给出了拉曼过程的新图像。半导体纳米管的热电性给出了限制效应对热电功率因数的一般概念。利用相干声子谱的脉冲串技术，提出了一种选择性激发单个声子模的方法。在碳纳米管量子点中的两个和四个折叠简并的发生被解释为不同的群速度和在布里渊区的六边形角附近的谷内/谷间散射。
In this article, we overview our recent theoretical works on electronic and optical properties of carbon nanotubes by going from the background to the perspectives. Electronic Raman spectra of metallic carbon nanotubes give a new picture of Raman processes. Thermoelectricity of semiconducting nanotubes gives a general concept of the confinement effect on the thermoelectric power factor. Selective excitation of only a single phonon mode is proposed by the pulsed train technique of coherent phonon spectroscopy. Occurrence of both two and four fold degeneracy in the carbon nanotube quantum dot is explained by difference group velocities and the intra/inter valley scattering near the hexagonal corner of the Brillouin zone.
