Carbon nanotubes Raman response theory

Project: Research

Project Details


The Raman spectroscopy is one of the most widespread techniques for the determination of atomic structure of carbon nanotubes. The growth of carbon nanotubes into nanocrystalline bundles and the resonant behavior of their Raman response make the spectra interaction difficult. We have been interested in the effect of the tube-tube interaction on their vibrational response. Force field method together with Lennard-Jones potential have been used. Finite and infinite size, homogeneous and inhomogeneous bundles have been considered, as well as multilayer compounds. We foccussed on the symmetry breaking effect on the intensity of the Raman actif modes and their frequencies as a funtion of the number of tubes.
