Surface enhanced resonance Raman scattering from radial and tangential modes of semiconducting single wall carbon nanotubes

Surface enhanced resonance Raman scattering experiments have been carried out on semiconducting single wall carbon nanotubes (SWNTs) adsorbed on mechanically polished rough silver foils. Stokes (S) and anti-Stokes (AS) spectra of both the tangential and the radial modes are studied as a function of...

Description
Summary:Surface enhanced resonance Raman scattering experiments have been carried out on semiconducting single wall carbon nanotubes (SWNTs) adsorbed on mechanically polished rough silver foils. Stokes (S) and anti-Stokes (AS) spectra of both the tangential and the radial modes are studied as a function of incident laser power. This yields the estimation of surface enhanced Raman scattering cross-section using vibrational pumping model. Results are compared with the earlier reports.
