Ion-irradiation effects in multi-walled carbon nanotubes were investigated. Atomistic computer simulations were used to study the defects, and their properties under single-ion impact and high-dose bombardment. The ion ranges were determined as a function of ion energy by using a binary-collision stochastic approach. The ability of multi-walled carbon nanotubes to stop energetic noble-gas ions, and the effects of the highly anisotropic atomic tube structure upon the ion ranges and defect distribution were also analyzed.
