Від 2022 року (НАКАЗ 31 ОД від 21.01.2022 року) кафедра має назву "Мікро- та наноелектроніка", первісна назва – "Фізичне матеріалознавство для електроніки та геліоенергетики". З 1.09.2024 р. (НАКАЗ 303 ОД від 28.08.2024 року ) кафедра "Радіоелектроніка" приєднана до кафедри "Мікро- та наноелектроніка"

Кафедра "Фізичне матеріалознавство для електроніки та геліоенергетики" була заснована у 1988 році з ініціативи Заслуженого діяча науки та техніки України, доктора фізико-математичних наук, профессора Бойка Бориса Тимофійовича.

(Sumy State University, 2017) Klochko, N. P.; Kopach, V. R.; Khrypunov, G. S.; Korsun, V. E.; Lyubov, V. M.; Otchenashko, О. N.; Zhadan, D. O.; Kirichenko, M. V.; Nikitin, V. О.; Maslak, M. O.; Khrypunova, A. L.
Nanostructured pristine lead sulfide and copper iodide semiconductor films as well as copper doped lead sulfide and iodine-enriched copper iodide layers were obtained on solid and flexible substrates via Chemical Bath Deposition (CBD) and Successive Ionic Layer Adsorption and Reaction (SILAR) methods. Crystal structures, optical, electric and thermoelectric properties of the layers have been studied. It was shown that the obtained films deposited on glass and mica substrates are smooth and continuous, have polycrystalline structures of the corresponding bulk semiconductors with grain sizes of several tens of nanometers. Investigations of the optical properties revealed, that their band gaps are characteristic for the corresponding bulk materials. All obtained semiconductor layers are p-type of conductivity. The resistivity of the lead sulphide films were reduced noticeably by means of their doping with copper. Iodination of the copper iodide films convert them into degenerate semiconductors. Investigations of the temperature dependent resistivity, the Seebeck coefficients and power factors confirmed that the obtained materials are promising for their use in thin-film solar thermoelectric generators with the aim of solar heat transforming into electricity.

Nanostructured ZnO and CuI Thin Films on Poly (Ethylene Terephthalate) Tapes for UV-Shielding Applications
(Sumy State University, 2020) Klochko, N. P.; Klepikova, K. S.; Zhadan, D. O.; Kopach, V. R.; Khrypunova, I. V.; Petrushenko, S. I.; Dukarov, S. V.; Lyubov, V. M.; Khrypunova, A. L.
In this work, we study a suitability for protection against terrestrial ultraviolet part of the solar spectrum of undoped and doped by indium zinc oxide thin nanostructured films, ZnO and ZnO:In, respectively, and cuprous iodide (CuI) films obtained via Successive Ionic Layer Adsorption and Reaction (SILAR) techniques on the lightweight low cost poly(ethylene terephthalate) (PET) flexible substrates. The film morphology is observed by scanning electron microscopy (SEM). Chemical compositions of the films are investigated by X-ray fluorescence (XRF) microanalysis. To research crystal structure we used X-ray diffraction (XRD) method. The UV-protection ability of the nanostructured thin films, PET tapes and samples consisting of the PET substrates and the films deposited on them by the SILAR method has been evaluated on the base of their optical properties in accordance with an international standard ISO 2443:2012(E) “Determination of sunscreen UVA photoprotection in vitro”. According to the research, nanostructured ZnO, ZnO:In and CuI thin films made by the cheap, affordable, and suitable for mass production SILAR method on thin flexible cheap PET substrates have been proposed as a new material for UV-shielding applications. In accordance with an international standard ISO 2443:2012(E), UV-protection ability of the samples consisting of the PET substrates and the films deposited on them by the SILAR method fits the category “excellent” (50+). The best low cost flexible and lightweight UV shielding material turned out to be that consisted from ZnO:In film and PET substrate, the sun protection factor of which equals 157.
Effect of Glow-discharge Hydrogen Plasma Treatment on Zinc Oxide Layers Prepared through Pulsed Electrochemical Deposition and via SILAR Method
(Sumy State University, 2019) Klochko, N. P.; Klepikova, K. S.; Petrushenko, S. I.; Nikitin, A. V.; Kopach, V. R.; Khrypunova, I. V.; Zhadan, D. O.; Dukarov, S. V.; Lyubov, V. M.; Khrypunova, A. L.
In this work, we investigated the effect of glow-discharge H₂⁺ plasma treatment on ZnO layers deposited on fluorine doped tin oxide (FTO) glass substrates through low temperature aqueous solution growth, namely, via a pulsed electrochemical deposition and by successive ionic layer adsorption and reaction (SILAR) technique. It is shown that the crystal structure, surface morphology, chemical composition and optical properties obtain some destructive changes after plasma processing due to the creation of oxygen vacancies Vo and H-related defects, and additionally, because of the zinc oxide etching by the glow-discharge H₂⁺ plasma through reduction of zinc oxide and evaporation of Zn from the surface. Neverthe-less, our investigations show quite good stability of the ZnO layers to the plasma-induced radiation and chemical impacts under high total H₂⁺ fluence received by every ZnO/FTO sample ~ 8·10¹⁸ cm⁻².

(Сумський державний університет, 2018) Klochko, N. P.; Klepikova, K. S.; Petrushenko, S. I.; Kopach, V. R.; Khrypunov, G. S.; Zhadan, D. O.; Dukarov, S. V.; Lyubov, V. M.; Kirichenko, M. V.; Surovitskiy, S. V.; Khrypunova, A. L.
The investigations of effect of long-wave (UVA) and short-wave (UVC) ultraviolet light of extraterres-trial solar irradiance on the nanostructured zinc oxide arrays, which were grown by pulsed electrodeposition, as well as on the ZnO and ZnO:In films produced by Successive Ionic Layer Adsorption and Reaction technique (SILAR) confirmed their suitability as UVA-active photosensitive materials. The crystal structure, surface morphology, chemical composition and optical properties found no obvious significant destructive changes after UVC irradiation. However, we detected some irreversible changes in the nature of point defects under the influence of UVC, which affect the ZnO and ZnO:In resistivity, activation energy, photosensitivity and thermoelectrical properties.
