It is found that the critical diameter for forming a stable nanoring can be made significantly smaller than that observed in experiments. The critical diameter for an armchair nanoring is smaller than that for a zigzag nanoring with the same nanotube diameter. The effect of torsion on a nanoring reduces its critical diameter. A large flattening of the nanotube cross section is found to be effective for the reduction in stress and stiffness of the nanoring. In addition, the instability of a nanoring always starts with the formation of short wavelength ripples on the compressed side of the nanotube. Subsequently, some ripples will develop into buckles, resulting in buckling failures. © 2005 The American Physical Society.||Source Title:||Physical Review B - Condensed Matter and Materials Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/106968||ISSN:||10980121||DOI:||10.1103/PhysRevB.72.115408|
