Résumé

Recently, we determined using spatial modulation spectroscopy, over a broad optical spectral range, the spectrum and amplitude of the absorption cross-section of individual semiconducting single-wall carbon nanotubes. Here, we will present resonant Raman excitation profiles (REP) of radial breathing modes and G modes measured on the same SWNTs. The transition energies and full width at half-maximum (FWHM) obtained using both measurements techniques will be compared to discuss the different models commonly used to fit REP as illustrated on Figure 1. Furthermore, interference effects on Raman intensity will also be evidenced in the case of two energetically close optical transitions. Finally, some recent results obtained on other systems (SWNTs homogeneous dimer and double-walled carbon nanotubes) will be briefly reported.
