IV. Raman Characterization of Nanotubes

We present our overall theoretical results on resonance Raman intensity for first and second order processes. By conbining with (1) optical processes matrix elements, (2) electro-phonon matrix elements, (3) elastic scattering matrix elements, and (4) exciton binding energy calculations, we can now calculating relative Raman intensity for different phonon modes as a function of laser energy, (n,m) and length. Further an excitonic effect on Raman intensity is a new important issue that we should clarify. Using the exction wavefunction, we modified the formula of exciton-phonon interaction matrix element for Raman intensity. Pressure effect will show an interference effect on Raman processes for metallic carbon nanotubes.
