Abstract

A comprehensive study of the effect of the cadmium source on chemical bath deposited cadmium sulfide thin films is reported. Four different cadmium sources, namely cadmium sulfate, cadmium chloride, cadmium iodide, and cadmium acetate have been used. Single-dip, for 15 minutes, as well as multi-dip depositions (four successive depositions for 8-12 minutes each) were carried out at 70oC on quartz substrates. The effect of changing the cadmium source on the film optical/electrical properties as well as the film thickness was studied. Hall Effect measurements were carried out for all films as well as Rutherford Back Scattering (RBS), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM).
