Abstract

Swift heavy ion irradiation can produce various defects in a target material. However, these defects not necessarily make the material terrible. There is possibility of modifying the properties to make it attractive and enhancing the materials. 150 MeV Ag12+ ions were irradiated on pure and cerium doped SBN films at various ion fluencies viz. 1 x 1011, 1 x 1012 and 5 x 1012 ions/cm2. The effect upon irradiation on the surface properties were studied using XRD measurements. Radiation induced amorphization of the surface at the higher fluence studies was ascertained both through XRD, PL. The surface defects produced after irradiations have been quantified by the way of measurements like average grain size, surface roughness for each of ion fluence through AFM studies. The trapping of charges after irradiation could be perceived from current density measurements. The results were inter correlated with the tools taken for study.
