Study on changes in structural properties of Ni/Cu dendrites under irradiation by He-particles

Structure and morphology is the basis for the development of functional nanomaterials with controlled properties for practical use. This work is aimed at studying the effect of irradiation with alpha particles on structural and conductive properties of Ni/Cu dendrites. Low-energy ions of He are selected to simulate the accumulation of transmutant helium, leading to swelling and defect formation in the structure, which can lead to a decrease in the operability of electronic devices. In the course of the study, doses were determined in which defects formed during irradiation lead to a decrease in operational characteristics of nanostructures.
