摘要：

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 R-t. Analytic forms of the self-consistent field are also presented far from the axis of the infinite tube, and well into its interior. (C) 2003 Elsevier Science Ltd. All rights reserved.
