Disordering of carbon nanotubes by ion bombardment

Abstract

In this work, the formation of defects during the ionic modification of carbon nanotubes was studied. It was shown that during the ionic modification of multiwalled carbon nanotubes, the defect formation mechanism is reduced not only to the formation of recoil atoms by ions, but also due to the thermal peak. It can be seen that the radial distribution function for the irradiated nanotube is significantly different from the radial distribution function of a heated 4000 K nanotube. In addition, disorder has a special character: in the case of ion irradiation, in contrast to heating.

Enhancing the Surface Properties and Structure of MWNTs by Effective Ion Beam Irradiation

“…The amorphization of MWNTs appears to be necessary for further raising the fluence up to 7 × 10 16 , Figure 4. The current findings show that the quantity of ion beam irradiation specified is important in controlling defect development and MWNT transition to amorphization [25].…”
