Changes in the structure and conducting properties of copper nanotubes as a result of bombardment with O3+ ions

Resumo

The results of targeted modification of the structure and properties of copper nanotubes by accelerated O³⁺ ions at a fluence of 1 × 10⁹ to 5 × 10¹¹ cm⁻² with an energy of 1.75 MeV/nucleon are reported. XHray diffraction methods have been used to study the dynamics of changes in the crystallite shape, dislocation density, and the orientation of copper nanotubes before and after irradiation. It has been shown that irradiation with accelerated ions has a significant effect on the change in texture coefficients and dislocation density. At a fluence of 1 × 10¹⁰ cm⁻² or higher, the accumulation of oxygen in the nanotube structure is observed, which leads to the appearance of oxide compounds.
