In this paper, the technology of synthesis of crystallites and nanocrystallites of nickel oxide on the surface of indium phosphide is described. This technology consists of two stages. In the first stage, porous indium phosphide is formed on the surface of a single crystal of indium phosphide. The formation of such a porous layer provides better adhesion to the surface of the sample. The second stage involves the preparation of the solution that contains nickel ions, application of this solution to the surface of porous indium phosphide, followed by annealing. As a result, NiO/NiC2O4∙2H2O/por--InP/mono-InP structure was formed. Surface morphological parameters were obtained using scanning electron microscopy and EDX-analysis of chemical composition. Chemical analysis confirmed the partial formation of nickel oxide from nickel oxalate layer by thermal annealing. Using scanning electron microscopy, it has been established that the crystallites have a large scatter in diameter, but they may be divided into three characteristic groups: macro-; meso-and nano-crystallites. Such structures may find prospects for application in electrochemical capacitors and lithium-ion batteries. Further research is needed for methodology improvement to obtain structures with predetermined controlled properties.
