Chirality analysis of horizontally aligned single-walled carbon nanotubes: decoupling populations and lengths

Author affiliations

Abstract

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.
