Study of Some Structural, Electrical Properties of CuS Thin Films Deposited by Chemical Spray Pyrolysis Method


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