  • Electrical Properties of Thermal Annealed in Vacuum Spray Deposited Al-Doped ZnO Thin Films 
    POTLOG, T.; LUNGU, I.; RAEVSCHI, S.; BOTNARIUC, V.; ROBU, S.; WORASAWAT, S.; MIMURA, H. (Tehnica UTM, 2019)
    Al-doped ZnO thin films have been prepared by spray pyrolysis, which facilitates the incorporation of a higher percentage of dopant atoms. The vacuum thermally annealed at 420 °C temperature thin films have been characterized ...
  • Electrophysical properties of nanometric CdS layers deposited by pulverization method 
    BANU, S.; BOTNARIUC, V.; GORCEAC, L.; COVAL, A.; CINIC, B.; CHETRUŞ, P.; RAEVSCHI, S. (Tehnica UTM, 2013)
    The objective of this paper is establishing of the optimum conditions for CdS layers deposition by pulverization method on glass substrates coated with a previously deposited tampon SnO2 layer, studies of their electrical ...
  • Exploitation of Ultra-porous Aerogalnite for Microwave Electromagnetic Interference Shielding 
    ALDRIGO, M.; DRAGOMAN, M.; BRANISTE, T.; IORDANESCU, S.; RAEVSCHI, S.; SHREE, S.; ADELUNG, R.; TIGINYANU, I. (Tehnica UTM, 2019)
    In this paper, we present the electromagnetic interference shielding properties of an ultra-porous and ultra-light GaN-based nanomaterial, which we will refer to with aeroGaN. The importance of the so-called X-band (8.2-12.4 ...
  • Growth of p-GaN on Silicon Substrates with ZnO Buffer Layers 
    RAEVSCHI, S.; GORCEAC, L.; BOTNARIUC, V.; BRANISTE, T. (Tehnica UTM, 2019)
    GaN layers on Silicon with ZnO intermediate layer were synthesized by using the HVPE (Hydride Vapor Phase Epitaxy) method. ZnO layers were deposited from solutions of zinc compounds in ethanol or water in two steps. At the ...
  • Guiding of endothelial cells targeted with semiconductor material nanoparticles 
    BRANISTE, T.; TIGINYANU, I.; HORVATH, T.; RAEVSCHI, S.; GRIDENCO, O.; CEBOTARI, S.; HILFIKER, A. (Technical University of Moldova, 2016)
    We found that ECs attract free NPs and, depending on the NP concentration, the cellular activity is slowed down resulting in lower cellular mobility. Nevertheless, cellular proliferation does not seem to be affected as ...
  • The Influence of Semiconductor Nanoparticles upon the Activity of Mesenchymal Stem Cells 
    BRANISTE, T.; COBZAC, V.; ABABII, P.; PLESCO, I.; RAEVSCHI, S.; DIDENCU, A.; MANIUC, M.; NACU, V.; ABABII, I.; TIGINYANU, I. (Tehnica UTM, 2019)
    In this paper, we report on the viability and proliferation of mesenchymal stem cells after exposure to different types of semiconductor nanoparticles.
  • Straturi de AlN crescute pe siliciu prin metoda reacțiilor chimice de transport cu urme de azot polimerizat 
    RAEVSCHI, S.; SPALATU, N.; GORCEAC, L.; BOTNARIUC, V. (Technical University of Moldova, 2017)
    Lucrarea este consacrată dezvoltării tehnologiei de obținere a straturilor epitaxiale de nitrură de galiu pe siliciu prin metoda HVPE (Hydride Vapor Phase Epitaxy). Sintetizarea GaN nemijlocit pe siliciu este complicat de ...
  • X-Ray Photoelectronic Spectroscopy of GaN, AlGaN layers, Grown on Silicon by the Chemical Transport Reactions Method 
    RAEVSCHI, S.; BOTNARIUC, V.; GORCEAC, L.; POTLOG, T.; DOBROMIR, M.; LUCA, D. (Tehnica UTM, 2015)
    Thin layers of GaN, and AlGaN were synthesized on Silicon substrates by chemical transport reactions method in the system (H2-NH3-HCl-Al-Ga).The composition of surface layers was studied by X-ray Photoelectron Spectroscopy ...
  • XRD and XPS of Cd2SnO4 Thin Films Obtained by Spray Pyrolysis 
    POTLOG, T.; BOTNARIUC, V.; RAEVSCHI, S.; DOBROMIR, M.; LUCA, D. (Tehnica UTM, 2015)
    Cd2SnO4 thin films with a 1:1 and 1:3 Sn/Cd weight ratio at different substrate temperatures were fabricated by spray pyrolysis. The structural and surface composition of these films by X-ray diffraction (XRD) and X-ray ...
  • ZnO Nanometric Layers Used in Photovoltaic Cells 
    BOTNARIUC, V.; GORCEAC, L.; COVAL, A.; CINIC, B.; GAUGAS, P.; CHETRUS, P.; LUNGU, I.; RAEVSCHI, S. (Tehnica UTM, 2019)
    The ZnO thin layers were grown on glass, InP and pInP-nCdS substrates from zinc acetate dissolved in water-acetic acid-methanol solution having a molarity of 0.2 M by using the spray method in the argon flow in the temperature ...
