    Thin films (1-10 μm thickness) of nanocomposites (NC) based on organic coordinated compound (OCC) Eu(TTA)2(Ph3PO)2NO3 (where TTA is thenoyltrifluoroacetonate (C8H5F3O2S), Ph3PO - triphenylphosphine (C6H5PO) and polymer – ...
  • Interaction of Bacteria With Nanostructured Zinc-oxide Thin Films 
    IVANOVA, Iliana A.; ANGELOV, Orlin; KRASTEVA, Liudmila; PESHKOVA, Tatiana; PAPAZOVA, Karolina; DIMOVA-MALINOVSKA, Doriana; DUSHKIN, Ceco D. (Technical University of Moldova, 2011)
    The effect of nanostructured ZnO thin films on one Gram positive and one Gram-negative bacterium is studied. The films are prepared by different methods: (i) RF magnetron sputtering of ZnO target in atmosphere of Ar (0.5 ...
  • Magnetotransport Properties of Ultrathin LaMnO3 Layers 
    SHAPOVAL, Oleg; BELENCHUK, Alexander; ZASAVITSKY, Efim; KANTSER, Valeriu; MOSHNYAGA, Vasily (Technical University of Moldova, 2011)
    We report the transport and magnetic properties of La-deficient ultrathin films of La1-8MnO3 (LMO) grown on SrTiO3 (STO) and engineered by using different interfacial layers. LMO layer and adjusting interface oxide (LaO-STO ...
  • Nanolamellar Structures of Oxide-AIIIBVI:Cd Semiconductors Type for use as Detectors of Radiation in the UV Spectral Region 
    DMITROGLO, L.; UNTILA, D.; CHETRUSH, P.; EVTODIEV, I.; CARAMAN, Iu.; LAZAR, G.; NEDEFF, V. (Technical University of Moldova, 2011)
    In the paper, optical and photoelectrical properties of GaSe and InSe single crystal films of 10-5÷10-7 m submicron thickness and of semiconductor-native oxide structures obtained by annealing at (450÷700)°C in a normal ...
  • Nanoporous Zinc Oxide Films Prepared by Magnetron Sputtering 
    GHIMPU, L.; LUPAN, O.; POPESCU, L.; TIGINYANU, I. M. (Technical University of Moldova, 2011)
    In this paper we demonstrate an inexpensive approach for the fabrication of nanoporous zinc oxide films by using magnetron sputtering. Study of the structural properties proves the crystallographic perfection of porous ...
  • Optical Properties of Amorphous As-Se Thin Films 
    HAREA, D. V.; IOVU, M. S.; BENEA, V. G.; COLOMEICO, E. P.; COJOCARU, I. A. (Technical University of Moldova, 2011)
    Photostructural transformations in amorphous films of chalcogenide glasses (ChG) under light irradiation present scientific and practical interests. From scientific point of view, because the composition of ChG determine ...
  • Optical Properties of Phase Change Memory Ge1Sb2Te4 Glasses 
    IOVU, M. S.; COLOMEICO, E. P.; BENEA, V. G.; ANDRIESH, A. M. (Technical University of Moldova, 2011)
    Phase change memory materials are promising for the next-generation of non-volatile flash memory that will serve in new mobile computing, entertainment and other handheld electronics. Among them are chalcogenide glasses ...
  • Topological Insulator Materials and Nanostructures for Future Electronics, Spintronics and Energy Conversion 
    KANTSER, Valeriu (Technical University of Moldova, 2011)
    Two fundamental electrons attributes in materials and nanostructures - charge and spin – determine their electronic properties. The processing of information in conventional electronic devices is based only on the charge ...
