Targeted Modification of Ni Nanotubes by Electron Irradiation

Аннотация

Electron beam irradiation of metallic nanostructures is an effective tool for the controlled modification of the structural and conductive properties of materials. Irradiation at electron energies under 500 keV ensures controlled defect annealing in nanotubes, improving their conductive properties due to a decrease in their resistivity. At the same time, irradiation doses above 150 kGy lead to destruction of the samples due to local thermal heating of the nanotubes, which causes breakdown of their crystal lattice and amorphization of the samples.
