Surface charge model of a carbon nanotube: self-consistent field from Thomas–Fermi theory Original Research Article

A model of a C nanotube is set up and solved self-consistently by numerical methods using the Thomas–Fermi statistical approach to treat the C 2s and 2p valence electrons. In the model presented here the C4+ ions are ‘smeared out’ uniformly over the surface of an infinitely long cylinder of radius Rt. Analytic forms of the self-consistent field are also presented far from the axis of the infinite tube, and well into its interior.
