Influence of Substrate Temperature on Structural Properties of CdS Thin Films Prepared by Chemical Spray pyrolysis

Abstract

Abstract:

In the present work,  CdS thin films have been prepared by chemical spray paralysis method on glass substrate with different temperature from cadmium nitrate with constant thickness (440 ± 10 nm), to  study the effect of the  substrate  temperature  on structure properties of prepared films.

The results of structural measurements showed through a Scanning Electron Microscope (SEM) for the homogeneity of the prepared films, and from the results of an Atomic Force Microscope (AFM) the nanoparticles are the composition and the square root value of the average roughness (RMS )  of the thin films is equal   ( 0.699nm ). And from  X-ray diffraction pattern the results showed that all the films are polycrystalline, hexagonal structure, grain size within the range of nano scale, and substrate temperature does  not  affect on the crystal structure of the films, and prepared  film  has  a preferred  orientation  along (002) (i.e., the axis C perpendicular to the substrate).
