Changes in structure and conduction type upon addition of Ir to ZnO thin films
Zubkins, Martins; Kalendarev, Robert; Gabrusenoks, Jevgenijs; Plaude, A. V.; Zitolo, Andrea; Anspoks, Andris; Pudzs, Kaspars; Vilnis, Kaspars; Azens, Andris; Purans, Juris (Elsevier B.V., 2017)Zn-Ir-O (Zn/Ir ≈ 1/1) thin films have been reported to be a potential p-type TCO material. It is, however, unknown whether it is possible to achieve p-type conductivity at low Ir content, and how the type and the magnitude ... -
Comparative ab initio calculations of reo3, srzro3, bazro3, pbzro3 and cazro3 (001) surfaces
Eglitis, Roberts; Purans, Juris; Gabrusenoks, Jevgenijs; Popov, Anatoli I.; Jia, Ran (MDPI AG, 2020)We performed, for first time, ab initio calculations for the ReO2-terminated ReO3 (001) surface and analyzed systematic trends in the ReO3, SrZrO3, BaZrO3, PbZrO3 and CaZrO3 (001) surfaces using first-principles calculations. ... -
Impact of thermal treatment on the surface of na0.5bi0.5tio3-based ceramics
Bikse, Liga; Dunce, Marija; Birks, Eriks; Kundzins, Karlis; Freimanis, Otto; Livins, Maris; Gabrusenoks, Jevgenijs; Sternberg, Andris (Multidisciplinary Digital Publishing Institute (MDPI), 2021)Thermal etching is a widely accepted surface treatment method for studying microstructure in Na0.5Bi0.5TiO3-based compositions. Surprisingly, besides the flat pattern of grains (suitable for evaluating ceramics’ microstructure), ... -
Luminescence Properties of Epitaxial Cu2O Thin Films Electrodeposited on Metallic Substrates and Cu2O Single Crystals
Trinkler, Laima; Dai, Dajin; Chang, Liuwen; Chou, Mitch Ming-Chi; Wu, Tzu-Ying; Gabrusenoks, Jevgenijs; Nilova, Dace; Ruska, Rihards; Berzina, Baiba; Nedzinskas, Ramunas (MDPI, 2023)The luminescent properties of epitaxial Cu2O thin films were studied in 10–300 K temperature range and compared with the luminescent properties of Cu2O single crystals. Cu2O thin films were deposited epitaxially via the ... -
Mass recovery of carbonated fabrics of glass fibres after isothermal heating
Pentjuss, E.; Balodis, J.; Vdovicenko, M.; Gabrusenoks, Jevgenijs; Bajars, Gunars; Petersone, L.; Kleperis, Janis (Institute of Physics Publishing, 2019)Leaching of Na+ ions in sodium oxide (Na2O) and silica (SiO2) containing glass is well investigated mainly due to its weak weathering. The object of this study was naturally (at room conditions) leached, steady state product ... -
Phase transitions and upconversion luminescence in oxyfluoride glass ceramics containing Ba4Gd3F17 nanocrystals
Krieke, Guna; Sarakovskis, Anatolijs; Ignatans, Reinis; Gabrusenoks, Jevgenijs (Elsevier B.V., 2017)Novel transparent Er3+ doped oxyfluoride glass-ceramics containing Ba4Gd3F17 nanocrystals were prepared by melt quenching followed by heat treatment of as-prepared glasses. The phase composition and microstructure were ... -
Reactive pulsed direct current magnetron sputtering deposition of semiconducting yttrium oxide thin film in ultralow oxygen atmosphere: A spectroscopic and structural investigation of growth dynamics
Arslan, H.; Aulika, Ilze; Sarakovskis, Anatolijs; Bikse, Liga; Zubkins, Martins; Azarov, A.; Gabrusenoks, Jevgenijs; Purans, Juris (Elsevier, 2023)An experimental investigation was conducted to explore spectroscopic and structural characterization of semiconducting yttrium oxide thin film deposited at 623 K (±5K) utilizing reactive pulsed direct current magnetron ... -
Unraveling the Structure and Properties of Layered and Mixed ReO3–WO3 Thin Films Deposited by Reactive DC Magnetron Sputtering
Polyakov, Boris; Butanovs, Edgars; Ogurcovs, Andrejs; Sarakovskis, Anatolijs; Zubkins, Martins; Bikse, Liga; Gabrusenoks, Jevgenijs; Vlassov, Sergei; Kuzmin, Alexei; Purans, Juris (American Chemical Society, 2022)Tungsten trioxide (WO3) is a well-known electrochromic material with a wide band gap, while rhenium trioxide (ReO3) is a “covalent metal” with an electrical conductivity comparable to that of pure metals. Since both WO3 ...
