INFLUENCE OF VARIOUS FACTORS ON THE COMPOSITION OF ELECTRODEPOSITED THIN FILMS Mo–S

The work is devoted to the study of the influence of various factors – temperature, concentration of components in the electrolyte and current density on the composition of electrodeposited thin semiconductor Mo–S films. Obtained results show that with increasing Na2MoO4 concentration, temperature and current density, the amount of molybdenum in cathode deposits increases. The concentration of Na2SO3 influences the amount of molybdenum in the obtained films, respectively. It is established that black, uniform, crystalline, shiny coatings of the alloy Mo–S2 are obtained in 333–338 K temperature range, 7 mA/cm2 current density from electrolyte with the composition of 1.0 М Na2МоO4•2H2O and 0.1 М Na2SO3
