ABSTRACT WITHDRAWN

This report is based on study of defect clusters or amorphous matrices induced in nickel nanowires (Ni-NWs) due to interaction of a beam of ~ 60 KeV hydrogen (H+) ions. Ni-NWs are exposed to various fluencies of hydrogen (H+) ions ranging between ~ 1014 ions/cm2 to 1017 ions/cm2. The analysis of pristine and hydrogen (H+) ions irradiated Ni-NWs samples has been mainly done using scanning electron microscopy (SEM), transmission electron microscopy (TEM) and x-ray diffraction (XRD) techniques. SRIM (stopping range of ions in matter) simulation is performed to corroborate the production of defect clusters/amorphous matrices in Ni-NWs theoretically. Moreover, basic insight of defect creation in Ni-NWs due to interaction of low energy in kilo-electron-volt (KeV) range hydrogen (H+) ions has been built using collision cascade theory. The purpose of this analysis is to explore the possibility of application of Ni-NWs based future nanodevices in environment containing plenty of hydrogen (H+) ions such as for use in spacecrafts employed for upper space missions.
