The multiple electron transfer to finite length single walled carbon nanotubes were theoretically investigated via simulation of the linear sweep voltammetry. The energy levels of the investigated carbon nanotubes of various length and radius were obtained via the tight-binding method and the respective single electron charging energies were calculated. These two energetics were combined to understand the peak positions obtained in the calculated voltammogram. Mapping the peak potentials for different nanotube geometries suggest that the energy level structure and their dispersion in k-space may be experimentally obtained via voltammetric techniques.
