Abstract

The Fermi energy dependence of the G -band resonance Raman spectra of single-wall carbon nanotubes (SWNTs) is calculated, including the Kohn anomaly effect for metallic tubes. The gate voltage dependence of the G -band Raman spectra for SWNTs shows chirality-dependent G+ / G- spectra, reflecting their dependence on the eigenvector direction of the optical (LO and TO) phonon modes and the nanotube chirality.
