摘要
报道了用卷曲法对一系列手性单壁碳纳米管计及卷曲效应声子振动谱的计算结果.基于实际的数值计算,讨论了Brillouin区中心Γ点手性管晶格振动模的分类;得出了其12个非简并的本征频率与手性和管径的关系.
The phonon frequencies at the center of Brillouin zone in a series of ehiral single-wall carbon nanotubes were calculated numerically, in which the curvature effect was treated appropriately. According to the numerical results, the classification of the vibration modes for ehiral tubes at the center of Brillouin zone were analysed. The relations between frequeney-ehirality and frequency-tube diameter for 12 non-degenerate vibration modes Were illustrated.
