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.

За час існування кафедри в галузі електроніки на основі тонкоплівкових моделей були розроблені: нові технологічні методи виготовлення надійних конденсаторів на основі танталу та ніобію, елемент захисту електронних схем від імпульсних перепадів напруги, що не має світових аналогів, резистивний газовий датчик адсорбційно-напівпровідникового типу для аналізу навколишнього середовища тощо.

Кафедра входить до складу Навчально-наукового інституту комп'ютерного моделювання, прикладної фізики та математики Національного технічного університету "Харківський політехнічний інститут".

У складі науково-педагогічного колективу кафедри працюють: 1 доктор технічних наук, 4 кандидата технічних наук, 2 кандидата фізико-математичних наук; 3 співробітника мають звання доцента, 2 – старшого наукового співробітника, 1 – старшого дослідника.

Mathematical Modeling of Physical Processes of Electromagnetic Field Transformation in Elastic Oscillations Field in Microthick Layers of Metals
(Сумський державний університет, 2017) Plesnetsov, S. Yu.; Migushchenko, R. P.; Petryschev, O. N.; Suchkov, G. M.; Khrypunov, G. S.
The results of the mathematical studies on the modeling of high-frequency electromagnetic field conversion in the field of elastic oscillations process in microthick surface layers or electrically conductive ferromagnetic material thin films placed in a magnetic field are given, taking into account the coherence of elastic, electric and magnetic properties of the metal. It is shown that in practical calculations, especially in the case of high-frequency oscillations, it is necessary to take into account thickness of skin layer in which electromagnetic field transforms into acoustic field.
Nanostructured Thermoelectric Thin Films Obtained by Wet Chemical Synthesis
(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.

Dependence of minority charge carriers lifetime on point defects type and their concentration in single-crystal silicon
(Scientific and Technological Corporation "Institute for Single Crystals", 2011) Zaitsev, R. V.; Kirichenko, M. V.; Doroshenko, A. N.; Khrypunov, G. S.
Using the computer simulation method it was studied the dependences of nonequili-brium electrons lifetime from concentration of elementary bulk point defects and various complexes of the bulk point defects, which may be present in the diode structures based on p-type conductivity boron doped silicon crystals with 10 Ohm-cm resistivity, grown by the Czochralski method. A number of obtained results well correlated with the experimental data related to the effects of photon degradation in solar cells which based on considered type silicon crystals (Si-SC) and influence of a stationary magnetic field on such devices efficiency. Overall, our results provide additional possibility for the evolution features prediction of electronic, and consequently, functional parameters, not only for Si-SC, but also for other devices based on such diode structures. It will allow looking for the most efficient and cost effective ways to optimize their design-technological solutions, and also estimates their reliability and durability level.
Single-crystal silicon solar cell efficiency increase in magnetic field
(Scientific and Technological Corporation "Institute for Single Crystals", 2010) Zaitsev, R. V.; Kopach, V. R.; Kirichenko, M. V.; Lukyanov, E. O.; Khrypunov, G. S.; Samofalov, V. N.
It is established in experiment that efficiency of unijunction (UJ) single-crystal silicon solar cells (Si-SC) with horizontal n⁺-p-p⁺ diode structure may increase by a factor of approximately 1.1 after their holding at room temperature during 7 days in perpendicularly oriented stationary magnetic field with 0.2 T induction. The subsequent stabilizing of the obtained positive effect is shown to be realizable by attachment of a thin magnetic vinyl layer (creating in the UJ Si-SC base crystal a magnetic field with induction not exceeding 0.05 T) to the UJ Si-SC at the back electrode side.

(Sumy State University, 2017) Zaitsev, R. V.; Khrypunov, G. S.; Veselova, N. V.; Kirichenko, M. V.; Kharchenko, M. M.; Zaitseva, L. V.
For the purpose of creation of thin-film photoelectric converters on the basis of sulfide and telluride of cadmium the pilot studies of process of magnetron dispersion on a direct current of telluride of cadmium and influence of the modes of magnetron dispersion on crystalline structure of films of CdTe are conducted. CdTe films for basic layers of sheet photoelectric converters on flexible polyimide substrate by the method of magnetron dispersion on a direct current are received for the first time. It is experimentally shown that "chloride" processing of the received layers of telluride of cadmium leads to transformation of metastable hexagonal modification of telluride of cadmium in stable cubic. At the same time at the expense of the eutectic recrystallization body height of the sizes of areas of a coherent dispelling much and decrease by 1,5 times of level of microstrains is observed.
