摘要
The total potential energy of the C-60 chains within the single walled carbon nanotubes (SWNTs) has been calculated by employing the van der Waals potential and tight binding molecular dynamics. The obtained results show that, under some conditions, the C-60 molecules can be dimerized within (9, 9) tube, (16, 0) tube or some other tubes of larger diameters. The dimerization structure is shown to be more stable than the equally separated C-60 structure. It is also found that the dimerization of C-60 molecules depends on the space between the nanotube and the encapsulated C(60)s, rather than on the nanotube chirality. (C) 2004 Elsevier B.V.
