Abstract:
The following research represents the investigation of un-doped nanostructured zinc sulfide thin films, and has a different dopant weight ratio of nickel (2, 4) wt. %, was deposited on glass substrate by the DC magnetron sputter method. X-ray diffraction pattern, scanning electron microscope and atomic power microscope were studied. All the membranes recorded with the pattern of polycrystalline with dominant reflection at (100) plane. The intensity of this reflection and its crystallite size increases from 8 nm to 11.86 nm with the increase of doping ratio of nickel, and that the surface of all the films was homogeneous with the growth of clusters of ZnS: Ni on the surface from growth seeds ZnS. While the AFM images showed a low conical shape base down, the average surface roughness and the height of the cone and their number increases .with increasing doping ratio, while the doping process reduces the values of the optical energy gap from 3.75 eV to 3.5 eV when increasing the doping ratio to 4wt. %.
