Abstract
Electrodeposited cadmium sulfide CdS on nickel substrate of new properties from aqueous solutions of Cd2+ and S2O3 2− at 313 K has been obtained using cyclic voltammetric and potentiostatic techniques The mechanism of the electrode reactions for the electrodeposition of CdS has been evaluated and proposed Energy dispersive Xray florescence elemental analysis and Xray diffraction investigations demonstrate that the electrodeposited CdS is pure and hexagonal polycrystalline in nature at our optimal conditions Furthermore the electrodeposited CdS is of ntype semiconductor was investigated and confirmed by Mott–Schotky test Donor concentration ND was determined to be 10 × 1017 cm−3 In this research we discovered that the electrodeposited semiconductor CdS on Ni substrate has low resistivity and magnetic properties became as a strong magnet at the mentioned conditions The photoelectrochemical measurements of the electrodeposited CdS on nickel electrode had been investigated at room temperature and under illumination giving good results
