This article reviews the electronic and transport properties of carbon nanotubes. The focus is
mainly theoretical, but when appropriate the relation with experimental results is mentioned …

Nanoscale systems are forecast to be a means of integrating desirable attributes of
molecular and bulk regimes into easily processed materials. Notable examples include …

We present Raman spectroscopy measurements on single-and few-layer graphene flakes.
By using a scanning confocal approach, we collect spectral data with spatial resolution …

Raman spectroscopy is the inelastic scattering of light by matter. Being highly sensitive to
the physical and chemical properties of materials, as well as to environmental effects that …

A brief review is given of electronic and transport properties of carbon nanotubes obtained
mainly in ak· p scheme. The topics include a giant Aharonov–Bohm effect on the band gap …

Excitonic effects in the linear and nonlinear optical properties of single-walled carbon
nanotubes are manifested by photoluminescence excitation experiments and ab initio …

We present a comprehensive study of the chiral-index assignment of carbon nanotubes in
aqueous suspensions by resonant Raman scattering of the radial breathing mode. We …

We show that the optical absorption spectra of boron nitride (BN) nanotubes are dominated
by strongly bound excitons. Our first-principles calculations indicate that the binding energy …

We present a theoretical analysis and first-principles calculation of the radiative lifetime of
excitons in semiconducting carbon nanotubes. An intrinsic lifetime of the order of 10 ps is …

We investigate from first principles the optoelectronic properties of nanometer-sized
armchair graphene nanoribbons (GNRs). We show that many-body effects are essential to …
