利用晶体石英衬底上生长的单壁碳纳米管（SWCNTs）的排列形态以及系统的拉曼测绘测量，独立评估了具有不同手性（n,m）的SWCNTs的种群和长度。通过将径向呼吸模式频率与Kataura图进行比较，逐一分配SWCNTs的手性。通过拉曼映射和/或扫描电子显微镜确定swcnts长度。本研究中生长的直径为1.14至1.29 nm的SWCNTs的数量和长度与它们的手性角没有明显的相关性。
Utilizing the aligned morphology of single-walled carbon nanotubes (SWCNTs) grown on crystal quartz substrates together with systematic Raman mapping measurements, the populations and lengths of SWCNTs with different chiralities (n,m) were independently evaluated. Chiralities of SWCNTs were assigned on a one-by-one basis by comparing radial breathing mode frequencies with the Kataura plot. The SWCNT lengths were determined by Raman mapping and/or scanning electron microscopy. Both the populations and lengths of the SWCNTs grown in this study with a diameter of 1.14 to 1.29 nm showed no clear dependence on their chiral angles.
