  • Birefractive Effects in Crystals and Quantum Wells 
    ZALAMAI, Victor; SYRBU, Nicolae (Institutul de Fizică Aplicată al AŞM, 2017)
    Double refraction or birefringence is an effect of the light splitting into two components in anisotropic media. If a light ray falls perpendicular to the surface of the crystal, then on this surface it splits into two ...
  • Characterization of p-NiO/n-Si heterojunctions prepared by spin coating method 
    MORARI, Vadim; ZALAMAI, Victor; RUSU, Emil; MONAICO, Eduard; URSAKI, Veacheslav; NIELSCH, Kornelius; TIGINYANU, Ion (Academia de Ştiinţe a Moldovei, 2019)
    In this paper, we present results on preparation of NiO thin films by spin-coating method. The films have been deposited on n-Si (100) substrates from 0.35 M aqueous solution of nickel chloride - NiCl2 *6H2 O or nickel ...
  • Degree of mode localization in Random lasing from ZnO nanoparticles 
    FALLERT, Johannes; SARTOR, Janos; DIETZ, Roman J. B.; SCHNEIDER, Daniel; ZALAMAI, Victor; KLINGSHIRN, Claus; KALT, Heinz (IEEE, 2009)
    We present an experimental procedure to directly extract the degree of localization of random laser modes in ZnO powders. Strongly localized and extended modes are found to coexist within the same ensemble area.
  • Morphology, optical and luminescence properties of ZnO layers doped with Al or Ag and co-doped with rare earth ions 
    ROGACHEV, Alexander; SEMCHEMKO, A.; GAISHUN, V.; RUSU, Emil; URSAKI, Veacheslav; CURMEI, Nicolai; ZALAMAI, Victor (Romanian Academy Publishing House, 2017)
    In this paper we propose a method for measuring the negative refraction index of films of optically transparent materials. Morphological, optical and luminescence properties of rare earth doped ZnO layers prepared by a ...
  • Photoluminescence of Eu-doped ZnO structures 
    URSAKI, Veaceslav V.; RUSU, Emil; ZALAMAI, Victor; SIRBU, Lilian; MONAICO, Eduard; TIGINYANU, Ion M. (Society of Photo-Optical Instrumentation Engineers, SPIE, 2004)
    ZnO-based red phosphors were prepared by different methods. One phosphor was grown from a Na2B4O7 melt, and another one was prepared from a ZnO:Eu2O3 powder via electron beam treatment. The e-beam processing is found to ...
  • Proprietăți optice ale filmelor ITO:GA2O3 obținute prin pulverizare magnetron 
    SUMAN, Victor; RUSU, Emil; ZALAMAI, Victor; URSACHI, Veceslav; GHIMPU, Lidia (Universitatea de Stat din Moldova, 2021)
    Prin pulverizare magnetron (RF) pe substraturi de sticlă și safir au fost depuse filme ITO:Ga2O3. Ca sursă de evaporare au servit țintele confecționate din amestecul de pulbere ITO și Ga2O3 cu concentrația oxidului de galiu ...
  • Proprietăți optice ale filmelor ITO:GA2O3 obținute prin pulverizare magnetron 
    SUMAN, Victor; RUSU, Emil; ZALAMAI, Victor; URSACHI, Veceslav; GHIMPU, Lidia (Universitatea de Stat din Moldova, 2021)
    A fost studiat efectul majorării cantității de Ga2O3 din sursa supusă evaporării asupra transmitanței optice (T), reflectanței (R) și absorbanței (𝛼) a filmelor de ITO:Ga2O3.
  • Rezonatoare laser în nanostructuri de ZnO cu moduri de emisie controlate de morfologie 
    URSACHI, Veaceslav; RUSU, Emil; ZALAMAI, Victor; TIGHINEANU, Ion (Academia de Ştiinţe a Moldovei, 2011)
    The paper gives an overview of technological elaborations performed at the Institute of Applied Physics and the Institute of Electronic Engineering and Nanotechnologies “D. Giţu” of the Academy of Sciences of Moldova for ...
