Abstract / Description:We investigate the origin of the Breit-Wigner-Fano line in the
Raman spectra of individual single-walled carbon nanotubes and
their bundles. Using confocal Raman microscopy and atomic-force
microscopy we found that the Breit-Wigner-Fano line intensity
increases strongly with the bundle thickness. We confirmed this
result by Raman investigations of partially decomposed bundles,
which were additionally investigated by transmission electron
microscopy. Our random-phase approximation based theory, which
identifies the Breit-Wigner-Fano line as an excited band of
plasmon-phonon modes, is fully consistent with the experimental
results.
