    The electrical transport mechanism in the (nCdS–рAs2Se3) heterojunctions [Articol]
    (2008) Goglidze, Tatiana; Dementiev, Igor; Dmitriev, Serghei; Nasedchina, Nadejda; Mațcova, Natalia
    In the given paper we present results of I-V characterization of thin film heterojunctions on the basis of (nCdS)–(рAs 2 Se3 ). Structures have been obtained via spray pyrolysis deposition of polycrystalline nCdS layers on glass substrate and consecutive thermal vacuum deposition of the amorphous рAs 2 Se3 layers. The possible mechanisms of the current passing through obtained structure are discussed on the basis of results of I-V measurements performed at the different polarities and electrical field intensities in the heterojunction.

    Study of multiple record of the optical information on photothermoplastic mediums (PTPM) in the holographic way [Articol]
    (SPIE, 2007) Goglidze, Tatiana; Dementiev, Igor; Cortiucova, Iulia; Mațcova, Natalia
    In the given work results of experiments on carrying out of cyclic record on PTPM are resulted by holographic way. The optical scheme is resulted, allowing automating process of record of elementary holograms in the form of diffraction gratings on PTPM and their definitions diffraction efficiency. The mechanism of occurrence of "parasitic" memory PTPM due to photostructural transformations into thin layers CGS is considered.
