Abstract

In this research CuS thin films have been prepared by Spray pyrolysis to study their structural, electrical properties .The results of (X-Ray ) diffraction also illustrate that highest degree of phases purity can do obtained by increasing the concentration of copper salts , conversely , films may have multi-phase structure and incorporate impure insulator phases.The films ,which were prepared from copper chloride , develop the highest degree of phase homogeneity . The results of electrical measurements represented by Hall effect , resistivity and temperature variation of conductivity illustrate from the mobility of the charge carrier has value of (0.02~1.31cm2V -1s -1), Temperature variation of Conductivity has been explained in terms of occurrin in the films . Although , high activation energy (0.17~0.67eV) at relatively low temperature refers to the probability of involving ionic Conductivity.
