In the article by Telg and coworkers we find the Raman measurements on the bundle of one metallic and one semiconducting nanotube. "Correlating the resonance conditions of the RBMs and the high-energy modes, G + and G -, show that the G -peak originates from the metallic and the G + peak from the semiconducting tube". An asymmetric G -lineshape is observed, supporting "the idea that the Fano lineshape is an intrinsic property of metallic nanotubes". Moreover, the "observed G + and G - peaks originate from LO-phonons in semiconducting and metallic nanotubes, respectively". In the Figure by Telg and coworkers, we can see the Raman spectrum of the bundle, with a laser energy of 2.04 eV. The presence of two radial breathing modes is indicating that the system is made of two nanotubes. Using several different excitation energies, the researchers found that G -and G + peaks are due to different resonance conditions. "Therefore, the origin of the G -peak is a different nanotube than the tube related to the G + peak. This is in contrast to the common assumption for such lineshape where both peaks are attributed to metallic nanotubes" .
