Diffraction intensity and symmetry of single-wall carbon nanotubes

Abstract

We present a thorough full symmetry-based analysis of the diffraction space of single-wall carbon nanotubes. This enables direct insight into various effects of the tube's symmetry on intensity distribution, among which are the pattern's symmetry and orientational dependence. Also, some particular features of diffraction intensity are singled out. These are directly linked to a tube's symmetry parameters and therefore may give new valuable information about the tube itself. Finally, we discuss how these parameters can be determined from diffraction intensity distribution. © IOP Publishing Ltd.
