First-principles calculation of the electronic structure and energy loss near edge spectra of chiral carbon nanotubes

Autor: Lionel Calmels, Giovanni Bertoni

Publikováno v: Micron

We present first principles calculations of the electronic structure of small carbon nanotubes with different chiral angles theta and different diameters (d1 nm). Results are obtained with a full potential method based on the density functional theor
