摘要
在卷曲法计算得到的单壁碳纳米管12个非简并的本征频率与手性和管径关系的基础上,继续讨论了简并的本征频率中E1和E2的振动模式,以及其频率与手性和管径的关系.
The 12 non-degenerate phonon vibrational modes at the center of Brillouin zone for a series of single-wall carbon nanotubes have been analysed in a previous paper. The E1 and E2 of degenerate phonon vibrational modes are further discussed in this paper and the relations between frequency-chirality and frequency-tube diameter for E1 and E2 vibrational modes are also demonstrated.
