ScholarBank@NUS Repository. https://doi.org/10.1063/1.2976127||Abstract:||The oscillatory characteristics and the instability of double- and triple-walled carbon nanotube-based oscillators containing a vacancy or a Stone-Wales (SW) defect were investigated by molecular dynamics simulations. It was found that the existence of these defects markedly affects the oscillation period and amplitude. The defect-free oscillators are most stable, followed by oscillators containing a SW defect, while oscillators containing a vacancy are least stable. The origin of the defect-induced instability is due to the change in potential energy profile and the resulting force fluctuation. © 2008 American Institute of Physics.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/64849||ISSN:||00036951||DOI:||10.1063/1.2976127|
