Herein, proton ions beam irradiation induced coalescence of nickel nanowires (Ni-NWs) is studied using electron microscope techniques such as scanning and transmission electron microscopy (SEM and TEM). The coalescence process is found to progress via proton beam irradiation-induced local heating of Ni-NWs and collision cascade of atomic displacement mechanism from lattices of NWs, imposing an incessant restructuring of Ni atoms in individual NW lattices along adjacent NWs lead to assimilate two Ni-NWs together. Moreover, indication of amorphous structures or loss in crystal structure of Ni-NWs under proton ions beam irradiation is not found in the x-ray diffraction (XRD) analysis. This work may potentially be applied for developing complex metal nanowires networks for optoelectronic devices.
