Structural characterization of zinc sulphide thin films by radial distribution function analysis using x - ray scattering
In the present work we are interested in studies concerning the local structure of amorphous chemical bath deposited (CBD) ZnS thin films by using wide-angle X-ray scattering (WAXS) method. The effect of the thermal treatment on the amorphous ZnS thin films structure it is also evidenced. After the formulation of hypotheses on the local order of the chalcogenide system has been enounced, the radial distribution function (RDF) analysis was done and the atom coordinations were determined. The radius of the first coordination spheres was evaluated by using the correlation function g(r) resulted from the X-ray scattering measurements.
