The influence of deposition options (zinc ions concentration, cathodic current density and electrolysis duration) on ZnSe films formation is discussed. It is shown that the increase of film thickness and its porosity is observed at increase of current density and zinc ions concentration in electrolyte. The most compact films are formed when the zinc concentration in the electrolyte is less than 0.05 M and the current density is not higher than 35 mA/cm<sup>2</sup>. The obtained ZnSe film had p-type conductivity and a resistivity of 10<sup>5</sup>-10<sup>6</sup> Ohm·m. It was synthesized heterostructure ZnS/ZnSe/Ni including the p-n transition. The parameters of the diode heterostructure were determined by the dark IV-characteristic. |
