THE ELECTROCHEMICAL METHOD FOR OBTAINING THIN COVERINGS OF RHENIUM CHALCOGENIDES

This paper summarizes the publications in the last years. It analyzes more than 40 scientific papers on the production of rhenium chalcogenides by electrochemical method. A review using various electrochemical methods revealed the scientific basis of joint electrodeposition of rhenium with chalcogens patterns of different electrolytes and synthesized new semiconductor coating of rhenium chalcogenides. The electrolyte used sulfate, thiosulfate, chloride, borate, chloride and sulphate-alkaline solutions containing various concentrations of rhenium and chalcogen (S, Se, Te). Analysis of the results of measurements of cathode and anodic polarization curves for the joint electrodeposition of rhenium with the chalcogen (S, Se, Te) has shown that the co-deposition process is accompanied by depolarization, which proves the formation of a chemical compound or a solid solution based on these compounds and determines potential range in which to cathode stoichiometric compound are formed. It has been established that all of rhenium chalcogenides are semiconductor materials.
