Annotation The preparation of ZnSe films with sphalerite structure by electrochemical method in alkaline electrolyte (1-3 M NaOH solution, 0.5M Se) during selenization of zinc layer was described in this paper. Films formed agglomerated spherical particles with size of 0.5 – 1.5 m. The size of aglomerate decreases with increase of current density and time of selenization. Increase of NaOH concentration in the electrolyte leads to loss of continuity in the film by increasing their size. By varying the concentration of NaOH, selenization time and the current density it is possible to obtain the film of thickness 10.5 μm. The resulting ZnSe films have p-type of conductivity and resistivity 105 – 106 Оhm•m.
