Effect of Thickness to the Structure Properties of CdO Thin Films

Abstract

In this paper CdO thin films were prepared by using chemical bath depositionmethod. Three different thicknesses of CdO films (84.1nm, 165.1nm, 194.23nm) wereused .x-ray diffraction technique has confirmed the formation of cadmium oxide,where reveals the changes in films structure with thickness increase. Many structuralproperties and constants have been studied and calculated by using the formation fromXRD patterns and ASTM chart such as grain size, FWHM, integral breadth, shapefactor, texture coefficient, and number of layers .These structural constants wereplotted as a function of the films thicknesses. The results indicate that the high grainsize (21.557nm) which was calculated for crystalline plane (111) was corresponding tothe high film thickness (194.23nm), while larger number of layer obtained for the filmthickness 165.2nm.
