碳纳米管中的电荷增强:理论与实验

Electric charge enhancements in carbon nanotubes: Theory and experiments

Zhao Wang, Mariusz Zdrojek, Thierry Melin, Michel Devel

摘要:

我们提出了一个详细的研究微米长的单壁碳纳米管的电荷的静电增强效应,理论上使用原子电荷偶极子模型和实验静电力显微镜。我们表明,纳米管表现出在其两端令人惊讶的弱电荷增强,减少与纳米管长度和纳米管半径增加。理论和实验之间的定量协议。

英文摘要:

We present a detailed study of the static enhancement effects of electric charges in micron-length single-walled carbon nanotubes, using theoretically an atomic charge-dipole model and experimentally electrostatic force microscopy. We demonstrate that nanotubes exhibit at their ends surprisingly weak charge enhancements which decrease with the nanotube length and increase with the nanotube radius. A quantitative agreement is obtained between theory and experiments.
