Cadmium sulfide (CdS) thin films were deposited in an oscillating chemical bath using a Teflon vane connected to an electrical dental brush oscillating at 37 Hz. The range of the bath temperature was from 65 to 85 degrees C in intervals of 5 degrees C and different deposition times. By this agitation technique we obtained CdS films with a highly oriented hexagonal structure (alpha-greenockite) in the (002) direction as measured by X-ray diffraction patterns. Images of atomic force microscopy and stoichiometry values obtained by energy-dispersive analysis by X-ray confirm the good quality of deposited films. High stoichiometry on the CdS films was measured by elemental analysis with variations less than 3.5% in all samples. The mean value of the gap energy was about 2.38 eV, a close value for these films. (c) 2007 The Electrochemical Society.
