•Nanowires were synthesized via template-assisted electrodeposition method.•Copper oxide selenite nanowires were irradiated with 160 MeV, Ni+12 ion beam.•XRD confirmed no change in phase of irradiated nanowires.•Electrical resistivity of nanowires was found to decrease with the ion fluence.
Irradiation with swift heavy ions (SHIs) with energy in the MeV range is a unique tool for engineering the properties of materials. In this context, the objective of the present work is to study the conduction of charge carriers in pre- and post-ion-irradiated semiconducting nanowires. Copper oxide selenite nanowires were synthesized using a template-assisted electrodeposition technique from an aqueous solution of 0.8 M CuSO4·5H2O and 8 mM SeO2. The synthesized nanowires were observed to have a monoclinic structure with linear I–V characteristics (IVC). The effect of irradiation with 160 MeV Ni+12 ions on the properties of the copper oxide selenite nanowires was investigated for fluences varying from 1011 to 1013 ions/cm2. XRD spectra confirmed no change in the phase of the swift-heavy-ion-irradiated nanowires, but a modification in the orientation of the planes was observed that depended on the ion fluence. The electrical resistivity of the semiconducting nanowires also varied with the ion fluence. Simultaneous irradiation-induced modifications to the electro-chemical potential gradient and the granular properties of the material may have been the origin of the alteration in the structural and electrical properties of the nanowires.
