基于力常数模型计算了一系列扶手椅型、锯齿型和手性单壁BC3纳米管的声子色散关系.描述了单壁BC3纳米管结构的表征方式,比较详细地给出了其结构、对称性和晶格动力学分析.基于数值计算结果,讨论了拉曼活性模和红外活性振动模的频率与管径的关系.由分析结果做出推断,BC3纳米管的拉曼光谱和红外光谱比单壁碳纳米管更为复杂. The phonon dispersion relationship of a series of armchair, zigzag and chiral single-walled BC3 nanotubes was calculated based on the force constant model.The characterization of single-walled BC3 nanotube structure was described and the structure was given in detail. The symmetry Based on the results of numerical calculation, the relationship between the Raman mode of activity and the frequency of the infrared active vibration mode and the diameter of the tube is discussed. From the results of the analysis, the Raman and infrared spectra of BC3 nanotubes Single-walled carbon nanotubes are more complicated.
