抄録

We analyze the dependence of the second-order G′-band profile in terms of their (n,m) indices by measuring the resonance Raman spectra of several semiconducting and metallic isolated single wall carbon nanotubes. We show that this profile is very sensitive to the electronic structure, thus making it possible to get structural (n,m) information and to probe the splitting of the van Hove singularities in the electronic density of states due to the trigonal warping effect.
