Abstract:

Nickel nanowires (Ni-NWs) were purchased from Plasma Chem (Germany) with diameter in the range 200 to 300 nm. Ni-NWs were irradiated by copper ions beams to study the changes in their properties. Ni-NWs were exposed to copper ions beam of energies 30 keV, 40 keV and 50 keV and of fluence 1 X 1015 ions/cm2 at room temperature. Radiational effects of copper ions beam on the Ni-NWs structure and morphology were scrutinized by characterizing the sample using X-Ray Diffraction (XRD) and transmission electron microscopy (TEM). XRD results showed that characteristic peaks of un-irradiated and irradiated Ni-NWs having cubic phase. Intensities of the peaks were reduced by changing the energies of copper ions. Grain sizes were calculated by using Scherrer’s equation. Crystallite sizes were decreased by increasing the dose of copper ions. Lattice strain was also calculated which showed opposite behavior compared to crystallite size. Lattice strain increased by increasing the dose. TEM images revealed that radius of Ni-NWs reduced by copper ions beams irradiation.

Biography:

Dr. Shehla Honey is Assistant Professor of Physics at University of Okara, Pakistan. Her research focuses on ion irradiation-induced defects and characterize respective changes in physical properties of Nanowires (NWs), Nano rods (NRs) and Nanotubes (NTs) of metals and other 1D-nanostructures of various materials (e.g., semiconductor, metal oxides etc.) for applications in Nano devices. She was a PhD Fellow at University of the Punjab, Lahore from 2012 to 2017, where she developed the large-scale metal nanowires (MNWs) networks for the first time using ion irradiationinduced Nano scale welding of NWs.
