Item Substructural Properties and Anisotropic Peak Broadening in Zn(1-x)MnxTe Films Determined by a Combined Methodology Based on SEM, HRTEM, XRD, and HRXRD(Springer, 2016) Martinez-Tomas, С.; Климов, Олексій Володимирович; Климов, Алексей Владимирович; Klymov, Oleksii Volodymyrovych; Agouram, S.; Курбатов, Денис Ігорович; Курбатов, Денис Игоревич; Kurbatov, Denys Ihorovych; Опанасюк, Анатолій Сергійович; Опанасюк, Анатолий Сергеевич; Opanasiuk, Anatolii Serhiiovych; Muñoz-Sanjosé, V.Lattice deformation and extended defects such as grain boundaries and dislocations affect the crystalline quality of films and can dramatically change material’s properties. In particular, magnetic and optoelectronic properties depend strongly on these structural and substructural characteristics. In this paper, a combined methodology based on SEM, HRTEM, XRD, and HRXRD measurements is used to determine and assess the structural and substructural characteristics of films. This combined methodology has been applied to Zn1-xMnxTe films grown on glass substrates by close-spaced vacuum sublimation. Nevertheless the methodology can be applied to a wide variety of materials and could become a useful characterization method which would be particularly valuable in semiconductor growth field. The knowledge of the structural and substructural characteristics can allow not only the optimization of growth parameters, but also the selection of specific samples having the desired characteristics (crystallite size, minimum dislocation content, etc.) for high-quality technological devices.Item Investigation of Optical Properties of Magnesium Oxide Films Obtained by Spray Pyrolysis Technique(Odessa I. I. Mechnikov National University, 2016) Д`яченко, Олексій Вікторович; Дьяченко, Алексей Викторович; Diachenko, Oleksii Viktorovych; Опанасюк, Анатолій Сергійович; Опанасюк, Анатолий Сергеевич; Opanasiuk, Anatolii Serhiiovych; Курбатов, Денис Ігорович; Курбатов, Денис Игоревич; Kurbatov, Denys Ihorovych; Cheong, H.Today more and more areas of optoelectronics used oxide materials, as a result, their study, is very important . Therefore, in this paper, we study optical properties of magnesium oxide films. band gap, spray-pyrolysis, optoelectronics, optical properties.
