Effect of applied potential on the optical and electrical properties of CuCoO.

The effect of the applied potential on the crystallography, morphology, optical, and electrical properties of copper-cobalt oxide (CuCoO) co-electrodeposited on ITO (Indium Tin Oxide) substrate has been studied. The electrochemical behavior of CuCoO using cyclic voltammetry showed that the co-electrodeposition of CuCoO occurred at a negative potential of - 0.70 V versus SCE, following a quasi-reversible reaction controlled by the diffusion process.

Nucleation and growth of ZnTe thin layers electrodeposited on ITO substrate.

In order to develop materials able to guarantee optimal characteristics in terms of environmental compatibility, abundance, and photoactivity, zinc telluride (ZnTe) has become a great candidate for optoelectronic and photovoltaic device applications. In this work, on the basis of electrochemical techniques including cyclic voltammetry and chronoamperometry, it was found that the electrodeposition of zinc telluride (ZnTe) on indium tin oxide substrate (ITO) is a quasi-reversible reaction controlled by the diffusion process. The nucleation and growth mechanism follows the instantaneous three-dimensional process according to Scharifker and Hill model.

Electrochemical performance optimization of the polyaniline electrodeposited on ITO substrate.

We have elaborated polyaniline films on ITO substrate (indium tin oxide), by electrochemical process in different electrolytes (HCl, HSO, HNO, and HBO), which allowed us to study the effect of the counter ion on electrochemical energy storage performances of polyaniline as electrode material in supercapacitors. The study of the different obtained films performances was carried out by cyclic voltammetry and galvanostatic charge-discharge method and is interpreted by the SEM technique. We found that there is a clear dependence on the specific capacitance of the counter ion.
