The following chapter will review the resonant Raman-active modes of single-walled carbon nanotubes emphasizing the diameter dependence of the radial breathing mode and selectivity of the optical transition energies (resonance). Thermal studies of individual freestanding single-walled carbon nanotubes showed a pronounced phonon softening. The second part of the chapter is devoted to Raman imaging of graphene. This particular type of carbon nanophase has become available only recently. The first Raman signatures of few-layer to single-layer graphene flakes could be obtained and compared with scanning probe microscopy. The effect of electrical charging (doping) on the Raman features is also demonstrated. [ABSTRACT FROM AUTHOR] |
