  • Resonance Raman Spectroscopy in one-dimensional carbon materials
    Anais Da Academia Brasileira De Ciencias, 2006
    Co-Authors: Mildred S. Dresselhaus, Ado Jorio, Marcos A. Pimenta
    Abstract:

    Brazil has played an important role in the development and use of Resonance Raman Spectroscopy as a powerful characterization tool for materials science. Here we present a short history of Raman scattering research in Brazil, highlighting the important contributions to the field coming from Brazilian researchers in the past. Next we discuss recent and important contributions where Brazil has become a worldwide leader, that is on the physics of quasi-one dimensional carbon nanotubes. We conclude this article by presenting results from a very recent Resonance Raman study of exciting new materials, that are strictly one-dimensional carbon chains formed by the heat treatment of very pure double-wall carbon nanotube samples.

  • Double Resonance Raman Spectroscopy and optical properties of single wall carbon nanotubes
    AIP Conference Proceedings, 2004
    Co-Authors: Riichiro Saito, Alexander Grüneis, Ge. G. Samsonidze, Gene Dresselhaus, Ado Jorio, Luiz Gustavo Cançado, Cristiano Fantini, Marcos A. Pimenta, Jie Jiang, Mildred S. Dresselhaus
    Abstract:

    Recent progress on double Resonance Raman Spectroscopy and related optical properties of single wall carbon nanotubes (SWNTs) is presented. The electron‐photon and electron‐phonon interactions for graphite and SWNTs are calculated within the tight‐binding scheme. Optical absorption matrix element and phonon relaxation time calculations are consistent with experimental observations.

  • Double Resonance Raman Spectroscopy of single-wall carbon nanotubes
    New Journal of Physics, 2003
    Co-Authors: Riichiro Saito, Alexander Grüneis, Ge. G. Samsonidze, Victor W. Brar, Gene Dresselhaus, Mildred S. Dresselhaus, Ado Jorio, Luiz Gustavo Cançado, Cristiano Fantini, Marcos A. Pimenta
    Abstract:

    A review of double Resonance Raman Spectroscopy is presented. Non-zone centre phonon modes in solids can be observed in the double Resonance Raman spectra, in which weak Raman signals appear in a wide frequency region and their combination or overtone modes can be assigned. By changing the excitation laser energy, we can derive the phonon dispersion relations of a single nanotube.
