Show affiliationsDeep nanoindentation of a copper substrate by single-walled carbon nanotubes (SWCNTs) has been analyzed using molecular dynamics simulations. Three categories of SWCNTs and their relationship with temperature and nanotube length have been extensively investigated. The results of this comprehensive quantitative analysis for deep indentation demonstrate that only SWCNTs with relatively short lengths can indent into a substrate up to a desired depth without buckling. Most notably, a permanent hollow hole with a high aspect ratio will be produced on the copper substrate, while copper atoms in close proximity to the hole are only slightly disordered.
