The Synthesis of porous indium phosphide with nickel oxide crystallites on the surface

Abstract

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 nano­crystallites. 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.

“…Університети, які колись вирували науковим дискурсом, тепер або руїни, або перепрофільовані як тимчасові переміщені і існують в форматі «Університет без стін» (Suchikova, Tsybuliak, 2023) -евфемізм, який навряд чи охоплює величезні виклики системи освіти у вигнанні (Suchikova et al, 2023f) Це не просто зміна формату, а й дезінтеграція екосистеми -бібліотеки без книг, лабораторії без обладнання та класи без стін. Для таких галузей, як нанотехнології, які спираються на спеціалізовану матеріально-технічну базу (Suchikova et al, 2023e;Suchikova et al, 2022a;Suchikova et al, 2023c), ця ситуація є особливо руйнівною .…”

Characterization of CdxTeyOz/CdS/ZnO Heterostructures Synthesized by the SILAR Method

“…In recent years, oxide semiconductors, such as Ga 2 O 3 [34][35][36], NiO [37], and In 2 O 5 [38], have gained more and more importance and interest. They exhibit quite good optoelectronic properties and high stability due to surface self-passivation [39].…”

Advances in processing and characterization of conversion coatings

“…The effect of stainless steel annealing on the adhesion of TiO2 spray coating was discussed in [1]. Another novel approach to enhancing adhesion was proposed in [2], by a two-step synthesis of porous indium phosphide with nickel oxide crystallites, as a potential material in modern electronic instrumentation. The influence of ultrasound intensities on hydrodynamic conditions in copper coatings electrodeposition was analyzed in [3].…”
