ELECTRODEPOSITION OF CdS THIN FILMS UNDER A MAGNETIC FIELD

Abstract

In this study, for the deposition of CdS thin films, electrodeposition was employed and some of the depositions were carried out under a magnetic field. The effects of the magnetic field were investigated in detail. It was understood from the film thicknesses that the magnetic field reduced the reaction rate from 7.39 g/cm(2)s to 3.66 g/cm(2)s. X-Ray diffraction results showed that all the films were formed with a hexagonal structure. In addition, the crystallite sizes were calculated from these patterns and they varied between 35 nm and 15 nm, depending on the reaction rate. Ultraviolet-visible spectroscopy was used for estimating the energy band gap. The energy band gaps varied from 2.30 eV to 2.65 eV, depending on the reaction rates and, therefore, the magnetic field. When the scanning electron microscope images were examined, it was seen that the surfaces of the films that were obtained under the magnetic field were rougher.
