Nanoscale analysis of carbon nanotubes by tip-enhanced Raman spectroscopy (Conference Presentation)
Author(s): Yuji Kuwahara

Paper Abstract

We have investigated the tip-enhanced Raman spectra of carbon nanotubes on the metal substrate. The relationship between the 2D and G band intensities and the number of walls of a multiwalled carbon nanotube was elucidated, which enables spatial resolution of nanometer order. The 2D band to G band integrated intensity ratio was found to be sensitive to the number of carbon nanotube walls. Furthermore, the 2D band intensity was enhanced by the intertube interaction between carbon nanotubes. This phenomenon can be explained by quantum interference between Raman scattering paths resulting from the strong interaction between carbon nanotube walls.
