英文摘要: Spontaneous polygonization for a multiwalled carbon nanotubes (MWCNTs) without external pressure is understood by the competition between cohesion energy (with lattice mismatching and defect's effect) and curvature elastic energy of tubes inside the MWCNTs. Based on a continuum elastic model and perturbation analysis, the crucial conditions for spontaneous polygonization of MWCNT is expressed by fundamental parameters of MWCNTs, which are in reasonable agreement with all relevant experiments and computer simulations reported in literatures. Present approach can be used in further studies of crossectional geometry-dependent electronic properties of MWCNTs and other inorgnic nanotubes. (c) 2012 The Japan Society of Applied Physics
