Annotation Cadmium Selinide (CdSe) thin films prepared by thermal evaporation on glass substrates were irradiated with swift (100 MeV) Ni+7 ions at fluences of 1 × 1011 and 1 × 1012 cm – 2. The structural changes with respect to increasing fluence were observed by the means of X-ray diffraction (XRD). The modification in surface morphology and electrical properties has been analyzed as a function of fluence using XRD, AFM and I-V techniques. The AFM micrographs of irradiated thin films show the formation of small spherical grains and decrease in surface roughness with increasing fluence as well as I-V measurement revels that decrease in resistivity with increasing fluence.
