  • Aerosol Spray Deposited Wurtzite ZnMgO Alloy Films with MgO Nanocrystalline Inclusions 
    MORARI, Vadim; RUSU, E. V.; URSAKI, V. V.; NIELSCH, K.; TIGINYANU, I. M. (Springer, Cham, 2022)
    In this paper Zn1-xMgxO thin films with composition range x = 0.00–0.80 have been obtained by aerosol spray deposition method on p-Si substrates by using zinc acetate and magnesium acetate as precursors. The produced thin ...

    MORARI, V.; RUSU, E. V.; URSAKI, V. V.; NIELSCH, K.; TIGINYANU, I. M. (Universitatea Tehnică a Moldovei, 2021)
    In this paper Zn1-xMgxO thin films with composition range x = 0.00 – 0.80 have been obtained by aerosol spray deposition method on p-Si substrates by using zinc acetate and magnesium acetate as precursors. The produced ...
  • Exciton Spectra of CuAlS2 and CuAlSe2 Crystals 
    SYRBU, N. N.; URSAKI, V. V.; DOROGAN, A.; GALBIC, I.; KORZUN, B. V.; FADZEYEVA, A. A.; MIANZELEN, R. R. (Technical University of Moldova, 2009)
    The reflectivity exciton spectra are researched for CuAlS2 and CuAlSe2 crystals at 10K. The chipping values were calculated caused by the crystal field and spin-orbital interaction of valence zones. There have been estimated ...
  • Influence of close space sublimation processing upon the granular growth of thin-film CdTe solar cells 
    GHIMPU, L.; URSAKI, V. V.; POTLOG, T.; SIRBU, L.; TIGINYANU, I. M. (Technical University of Moldova, 2005)
    In this paper we study the impact of CSS processing parameters upon the morphology of CdTe/CdS solar cells.
  • Influence of source temperature upon the contamination with cu of thin-film CDTE solar cells grown by close space sublimation technique 
    GHIMPU, L.; URSAKI, V. V.; POTLOG, T.; TIGINYANU, I. M. (Technical University of Moldova, 2005)
    Photoconversion efficiencies up to 16.5 % have been attained from CdTe/CdS solar cells. CdTe/CdS heterojunction can be deposited cheaply over large areas using the close space sublimation (CSS) technique. In a previous ...
  • Luminescence and trapping of light in porous InP networks 
    MONAICO, E.; URSAKI, V. V.; BURLACU, A.; TIGINYANU, I. M. (Technical University of Moldova, 2005)
    In this paper we investigate the effect of light trapping inside highly scattering InP porous layers on the luminescence properties of the material.
  • Luminescence of porous ZnSe layers 
    MONAICO, E.; URSAKI, V. V.; BURLACU, A.; TIGINYANU, I. M. (Technical University of Moldova, 2005)
    In this paper we compare the luminescence properties of bulk ZnSe crystals and porous layers prepared by photon-assisted electrochemical etching.
  • Luminescence of ZnSe crystals grown with different vapor transport agents 
    ENACHE, M.; URSAKI, V. V.; RUSU, E. V.; TAZLAVAN, V. E.; SONTEA, V. P.; TIGINYANU, I. M. (Technical University of Moldova, 2005)
    In this paper we compare the luminescence properties of bulk ZnSe crystals grown by vapor transport method with different transport agents in order to establish the influence of the transport agent on the relation between ...
  • Optical Properties of TlGaS2 Crystals 
    MASHNIC, A.; NEMERENCO, L.; SYRBU, N. N.; URSAKI, V. V.; ZALAMAI, V. V. (Technical University of Moldova, 2013)
    The anisotropy of transmission spectra was investigated in TlGaS2 crystals. An intensive transmission line was found in samples placed between two crossed polarizers. Ground and excited states of excitons were detected in ...
  • Random lasers: 30 years of development 
    URSAKI, V. V. (Universitatea Tehnică a Moldovei, 2015)
    In this report an overview of random lasers development is presented staring from the first theoretical prediction of random laser action by Letokhov about 50 years ago and the first experimental demonstration by Markushev ...
  • Scattering Indicatrix for Absorbing Porous Medium with Dark Modes 
    SERGENTU, V. V.; MONAICO, E. V.; URSAKI, V. V. (Tehnica UTM, 2019)
    A mathematical model for calculation of the scattered radiation by a highly absorbing porous medium with dark modes is proposed. The contribution of the scattered light from two areas with the same slope was taken into ...
  • Zero Frequency Spectrum of 3-D Metal Photonic Crystals Obtained by the 3-D Kronig–Penney Model 
    SERGENTU, V. V.; URSAKI, V. V. (Tehnica UTM, 2015)
    We demonstrate in this work the possibility of the existence of ultrashort (dark) pure electrical modes at extremely low frequencies in a system of metallic nanospheres inserted into a dielectric material. These modes ...
