Abstract
Centimeter long single-walled carbon nanotube strands synthesized using chemical vapor deposition method were characterized using microscopy, micro-Raman spectroscopy, and small-angle X-ray diffraction techniques. The strands are large collections of well-aligned nanotube bundles, which consist of well-arranged single-walled nanotubes in a two-dimensional triangular lattice. The diameter of the single-walled nanotubes varies from 1.1 to 1.7 nm, with domination of the 1.1 nm tubes and the corresponding lattice constant of 1.42 nm.
