摘要: Standard enthalpies of formation (\(\Updelta_f H^{0}\)) finite-length (5, 5) single-walled carbon nanotubes (SWNTs) are calculated with the framework density functional theory. Approximate expressions have been proposed for both H-terminated and C30-capped SWNTs, based upon which values reproduced within several kilocalories per mole. It is also found that standard contributed by carbon, \(\Updelta_f H^{0}({\mathbf C}\)), oscillate increment cluster size, suggesting dependence relative stability on axial length.
