Abstract

Raman spectra of nitrogen-doped single-walled carbon nanotubes are calculated using the spectral moment's method combined with the bond polarizability model. The influence of the nanotube diameter and chirality is investigated. We also address the important question of the effect of the -doping concentration, and we propose an equation to estimate the doping concentration from the knowledge of the tube diameter and the frequency of the radial breathing mode.

摘要

利用光谱矩方法结合键极化率模型计算了氮掺杂单壁碳纳米管的拉曼光谱。研究了纳米管直径和手性的影响。我们还探讨了氮掺杂浓度影响这一重要问题，并提出了一个根据管直径和径向呼吸模式频率来估算掺杂浓度的方程。
