Resonant Raman Spectroscopy of Armchair Carbon Nanotubes: Absence of "Metallic" Signature

E. H. Haroz, J. G. Duque, W. D. Rice +3

The appearance of a broad peak at $\sim$1550 cm${}^{-1}$ (G${}^{-}$ peak) in carbon nanotube resonant Raman scattering spectra has been conventionally attributed to the presence of met…
