Query: Index assignment of a carbon nanotube rope using tip-enhanced Raman
  spectroscopy   We used tip-enhanced Raman spectroscopy to study the diameter-dependent Raman
modes in a contacted carbon nanotube rope. We show that with the near-field tip
enhancement a large number of nanotubes within a rope can be identified, even
if the nanotube modes can not be distinguished in the far-field signal. Several
metallic and semiconducting nanotubes can be identified and assigned to
nanotube families. Additionally, we provide a tentative chiral index
assignment.
