Preparation of Bi1-xSbx films by electrodeposition

A method has been developed to produce composition modulated Bi1-xSbx alloy s by electrodeposition. The electrolyte which consists of NaCl 4 M and HCl 1 M (pH 0) in aqueous medium, allows codeposition of bismuth and antimony t o be accomplished at room temperature on glassy carbon. The composition of the films, their crystal structure, morphology and resistivity were studied as a function of electrochemical parameters and bath composition. It is sh own that the electrodeposits are monophasic and exhibit a polycrystalline s tate. The obtained alloys represent a continuous series of solid solution. The film composition is dependent on the applied current density. The elect rical resistivity is of the order of 3-7 mu Ohm m.
