英文摘要: In this paper, the optimum diameter of stable single-walled carbon nanotubes (SWNT's) in a rope is calculated theoretically using its conformation energy, which consists of curvature elastic energy and intertube van der Waals energy. An equlibrium shape equation for single layer fullerenes is derived by means of variation of the conformation energy. For straight SWNT's in an SWNT rope, the solution to the equlibrium shape equation gives the optimum diameter to be 1.36 nm for stable SWNT's. This agrees well with the experimental observation [ Nature 388, 756 (1997) ; Science 273, 483 (1998) ].
