Electron irradiation-induced change of structure and damage mechanisms in multi-walled carbon nanotubes |
XPS results of (a) pristine MWCNTs, and (b) MWCNTs irradiated by 70 keV electrons with a fluence of 5 × 1015 cm−2. (c) The MWCNTs irradiated by 110-keV electrons with a fluence of 5 × 1015 cm−2. |
