“…After gamma and neutron irradiation, the non-linear IVC of copper nanowires was also observed in earlier studies (Rana and Chauhan, 2014;Gehlawat et al, 2012). Irradiation of photons and neutrons enhanced the number of charge carriers, while on the other hand; introduced more obstructions in the path of electrons in the form of defects.…”

“…As seen from spectra in figures 4(a)-(c), optical transmittance is less in the region of 374 nm which ultraviolet (UV) region of ultraviolet-visible (UV-vis) spectrum and absorption of light is strong in this area which may be attributed to effect of surface plasmonic resonance. If the dimension of nickel wires is in nanometer scale, absorbance band normally appear in UV precinct of UV-Visible spectra because of interaction of electromagnetic field will interact with conduction band electron in this band which arises effect of surface plasmonic resonance [27,28]. In this band, transmittance of light is reduced and scattering and absorption of light in UV region is increased.…”

Influence of 30 kilo-electron-volt (keV) Argon (Ar + ) ions on optical and electrical properties of nickel nanowires (Ni-NWs) meshes is being reported. Ni-NWs are being exposed to 30 keV Argon (Ar + ) ions at various beam fluencies. These fluencies of Ar + ions are 7×10 14 ions cm −2 , 3×10 15 ions cm −2 and 3×10 16 ions cm −2 . After irradiation, Ni-NWs meshes were analyzed through transmission electron microscopy technique (TEM). The structural analysis has been done through X-ray diffraction technique. It is found from TEM results that atoms are sputtered out from surfaces of Ni-NWs due to collision cascade effect persistently and lead to reduce the diameters or thicknesses of Ni-NWs. X-ray diffraction results reveal that crystalline quality is reduced under Ar + ions irradiation which may be due to defects induced in Ni-NWs as a result of collision cascade effect. The Ni-NWs meshes are characterized optically and electrically through UV-VIS spectroscopy and four probe techniques. The optical transparencies of Ni-NWs meshes are increasing with increase in beam fluence of Ar + ions. The electrical conductivity of the mesh is decreased continuously with increment in beam fluence of Ar + ions which might be due to production of defects in Ni-NWs. The tuning of optical transparency and electrical conductivity of Ni-NWs meshes is required for their application as successful transparent electrodes in optoelectronic nanodevices.

“…Analysis of published data revealed that several comprehensive studies had been performed on the effect of accelerated light and heavy ions on the transport properties of carbon-silica molecular sieves synthesized in channels of track-etched polymer membranes. Results of investigation of Zn [7], Cu [8][9][10], copper oxide selenite [11] and CdSeO 3 [12] nanostructures irradiated with ions of very high energy (on the order of (2.5-4.0) MeV/nucleon) followed by studying the properties of metallic nanostructures without removing the polymer matrix were reported. The effect of low-energy beams of heavy accelerated ions on the structure and transport properties of composite materials based on metal nanostructures and track-etched membranes has not been well experimentally studied [13].…”

This paper presents a case study of targeted modification of the structure and properties of zinc nanotubes ordered arrays by treatment with Xe +22 and Kr +17 swift heavy ions (SHI). Polyethylene terephthalate track-etched membranes (PET TeMs) with a pore density of (4 × 10 9 ) ions/cm 2 have been used as a template for electrochemical deposition of Zn. Scanning electron microscopy and energy dispersive analysis have been used for a comprehensive elucidation of the dimensionality, chemical composition of the synthesized samples. Dynamics of changes in the crystallite shape and orientation of NTs before and after irradiation has been studied by X-ray diffraction. Changes in conductive properties as a result of irradiation were discussed. After Xe +22 ions irradiation with a fluence of (1 × 10 11 ) m −2 or higher, the formation of loose areas in the structure of Zn NTs as a result of partial degradation of the crystal structure and, consequently, a decline in conductivity are observed. In case of Kr +17 ions, the increase in current conduction with the increase in fluence may be due to the increase in the current carriers.
