    Investigation of hgse films, deposited from aqueous solutions with different complexing agents
    (Видавництво Львівської політехніки, 2017-12-23) Chaykivska, Ruslana; Sozanskyi, Martyn; Stadnik, Vitalii; Guminilovych, Ruslana; Shapoval, Pavlo; Yatchyshyn, Yosyp; Lviv Polytechnic National University
    The process of synthesis of mercury selenide (HgSe) thin films by a chemical bath deposition method (CBD) with using different complexing agents (potassium rodanide, potassium iodide and sodium thiosulfate) has been investigated. The phase composition, crystal structure, absorption spectra, surface morphology of HgSe films were studied. The effect of nature of complexing agent on the properties of obtaining coatings was shown. The HgSe films have a sphalerite structure, nearly stoichiometric atomic ratios of mercury to selenium and optical band gaps, which are localized in the ranges 1.38-2.40 eV, depending on the usage of complexing agent.

    Investigation of some regularities of ZnS and ZnSe films synthesis
    (Lviv Polytechnic Publishing House, 2016) Sozanskyi, Martyn; Chaykivska, Ruslana; Guminilovych, Ruslana; Shapoval, Pavlo; Yatchyshyn, Yosyp; Lviv Polytechnic National University
    The process of synthesis ZnS and ZnSe thin films by a chemical bath deposition method (CBD) has been investigated. The phase composition, surface morphology and thickness of ZnS and ZnSe films were studied. The kinetic curves of ZnS and ZnSe synthesis was obtained and activation parameters were calculated. The correlation between thickness, morphology and activation energy have been established.

    Synthesis and properties of mercury selenide films deposited by using pottasium iodide as complexing agent
    (Lviv Politechnic Publishing House, 2017-01-20) Sozanskyi, Martyn; Stadnik, Vitalii; Chaykivska, Ruslana; Guminilovych, Ruslana; Shapoval, Pavlo; Yatchyshyn, Iosyp; Lviv Polytechnic National University
    Методом хімічного осадження ванн отри- мано плівки меркурій селеніду (HgSe) на скляних підкладках з використанням водних розчинів меркурій(II) нітрату, калій йодиду і натрій селеносульфату. Проведено рентгенофазовий та структурний аналіз отриманих зразків плівок за двох різних температур синтезу. Досліджено вплив тривалості осадження на оптичні та морфологічні властивості плівок HgSe. Обговорено механізм осадження.
