英文摘要	Chiral structure determination of single-walled carbon nanotube (SWNT), including its handedness and chiral index (n,m), has been regarded as an intractable issue for both fundamental research and practical application. For a given SWNT, the n and m values can be conveniently deduced if an arbitrary two of its three crucial structural parameters, that is, diameter d, chiral angle theta, and electron transition energy E-ii, are obtained. Here, we have demonstrated a novel approach to derive the (n,m) indices from the theta, d, and E-ii of SWNTs. Handedness and theta were quickly measured based on the chirality-dependent alignment of SWNTs on graphite surface. By combining their measured d and E-ii, (n,m) indices of SWNTs can be independently and uniquely identified from the (theta,d) or (theta,E-ii) plots, respectively. This approach offers intense practical merits of high-efficiency, low-cost, and simplicity.; Chemistry, Multidisciplinary; Chemistry, Physical; Nanoscience & Nanotechnology; Materials Science, Multidisciplinary; Physics, Applied; Physics, Condensed Matter; SCI(E); EI; 6; ARTICLE; 11; 5666-5671; 13
