  • STRATURI EPITAXIALE OMOGENE DE CdS OB ŢINUTE PE InP ÎN HIDROGEN 
    Raevschi, Simion; Gorceac, Leonid; Gaugaş, Petru; Botnariuc, Vasile (CEP, 2007)
    Epitaxial layers of the CdS on InP in the open flowing hydrogen system are obtained. Efficiency of zone method growth from a gas phase is shown at deposition of the homogeneous layers of large area.
  • STRATURI SUBŢIRI DE CdS DEPUSE DIN SOLUŢII LICHIDE (BAIE CHIMICĂ) 
    Botnariuc, Vasilii; Gorceac, Leonid; Coval, Andrei; Raevschi, Simion; Micli, Valdec; Cinic, Boris (CEP USM, 2011)
    Thin layers of CdS were deposited on InP (100) substrates with a (3...5) arc degrees misorientation relative to (110) using water solutions of CdSO4, (NH4)2SO4, NH4OH, NH4Cl and CS(NH2)2 for synthesis. The morphology, ...
  • STRATURI SUBŢIRI DE OXID DE ZINC CRESCUTE PRIN METODA PULVERIZĂRII ÎN FLUX DE ARGON 
    Botnariuc, Vasile; Gorceac, Leonid; Coval, Andrei; Cinic, Boris; Gaugaș, Petru; Chetruș, Petru M.; Moldovanu, Sergiu; Raevschi, Simion (CEP USM, 2018)
    Straturile subţiri de ZnO au fost crescute din acetat de zinc dizolvat în apă-acid acetic-metanol cu o molaritate de 0,2 M folosind metoda pulverizării în intervalul de temperaturi (250-450)°C în flux de argon. Au fost ...
  • STRUCTURA SUPRAFEŢEI STRATURILOR DE AlN DEPUSE PE Si PRIN METODA HVPE LA ETAPA INIŢIALĂ DE OBŢINERE 
    Raevschi, Simion; Kompan, Mihail; Zhilyaev, Yurii; Gorceac, Leonid; Botnariuc, Vasile (CEP USM, 2010)
    The surface structure of AIN layers deposited on the Silicon substrates at the initial stage of germination was studied by the Atomic Force Microscopy (AFM) method. The layers have been deposited by the Hydride Vapor Phase ...
  • TERAHERTZ SHIELDING PROPERTIES OF AERO-GaN 
    Braniste, Tudor; Dragoman, Mircea; Alyabyeva, Liudmila; Zhukov, Sergey; Ciobanu, Vladimir; Aldrigo, Martino; Raevschi, Simion; Dragoman, Daniela; Iordanescu, Sergiu; Shree, Sindu; Gorshunov, Boris; Adelung, Rainer; Tiginyanu, Ion (IOP Publishing Ltd, 2019)
    The electrodynamic properties of the first aero-material based on compound semiconductor namely of Aero-GaN, in the terahertz frequency region are experimentally investigated. Spectra of complex dielectric permittivity, ...
  • ZnO NANOMETRIC LAYERS USED IN PHOTOVOLTAIC CELLS 
    Botnariuc, Vasile; Gorceac, Leonid; Coval, Andrei; Cinic, Boris; Gaugas, Petru; Chetrus, Petru; Lungu, Ion; Raevschi, Simion (Springer Nature, 2020)
    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 ...
