Abstract

Individual single-wall carbon nanotubes (SWNTs) or thin ropes of SWNTs were characterized in position and size by Scanning Force Microscopy (SFM). Raman spectra of these objects could be obtained and were found to be comprised of well-resolved peaks. The orientation-dependent measurements reveal maximum intensity of all Raman modes when the nanotubes are aligned parallel to the polarization of the incident laser light. This clearly deviates from the selection rules predicted by theoretical studies and may be explained by depolarisation effects caused by the anisotropic geometry of the nanotubes and by electronic resonance effects.
