This is an introductory textbook for graduate students and researchers from various fields of science who wish to learn about carbon nanotubes. The field is still at an early stage, and progress continues at a rapid rate. This book focuses on the bas
This article examines the optical properties of single-wall carbon nanotubes (SWNTs) and nanographene. It begins with an overview of the shape of graphene and nanotubes, along wit the use of Raman spectroscopy to study the structure and exciton physi

Using the Bethe-Salpeter equation, we have calculated the exciton energies of (i) bright exciton states; (ii) 2g exciton energies; and (iii) the energy difference between dark and bright exciton states for single wall carbon nanotubes (SWNTs) as a fu

The use of the Fourier expansion technique, which is based entirely on crystal symmetry, is studied by application of the technique to the phonon dispersion relations in silicon and germanium. In order to facilitate the convergence of the Fourier exp

An effective Hamiltonian which yields the observed optical properties of silicon and germanium is presented. The form of the Hamiltonian depends upon crystal symmetry and is based on a Fourier expansion for the energy bands. This Hamiltonian is close

Recent Raman scattering studies in different types of graphene samples are reviewed here. We first discuss the first-order and the double resonance Raman scattering mechanisms in graphene, which give rise to the most prominent Raman features. The det

We have measured the Raman spectra of one to three layer graphene as a function of laser excitation energy. The observed G ′ band Raman peak (∼2650 cm −1 ) intensity decreases with increasing numbers of graphene layers. The electronic energy ba

The higher lying exciton energies ( E 33 S and E 44 S ) of single wall carbon nanotubes (SWNTs) are calculated by solving the Bethe–Salpeter equation within an extended tight binding method. For E 11 S and E 22 S transitions, the chirality dependen

A big picture view of Raman scattering in carbon nanotubes is presented, starting from its early history and the discovery of the unique Raman spectra of carbon nanotubes, and following on to the discovery of Raman spectra at the single nanotube leve
