Abstract
Electrodeposition is a low cost alternative and a very important technique to deposit either metals or semiconductors. This method allows the deposition of required quality thin film or coating over any conducting substrate with precise control over the deposition parameters. In this paper, efforts have been made to fabricate CdTe thin films from aqueous electrolytic bath at room temperature. To do this, cyclic voltammetric study of each component was carried out and the potential was selected which can lead to the deposition of CdTe films without the external thermal energy in form of increased bath temperature. It will be shown that the growth of this compound semiconductor is possible by combining under and over potential deposition techniques for two individual species. The surface morphology of the films was imagined by using scanning electron and atomic force microscopy. The optical study of the films was done by using spectrophotometer in the wavelength range of 200-1000 nm.
