    In this study the deformation peculiarities of aluminophosphate glasses (Li2O-Al2O3-BaO-La2O3-P2O5) doped with Dy, Tb and Fe were investigated at concentated load action (indentation) and uniaxial compression. Dynamic ...
  • Microstructuring of silicon crystal surface for solar cell application 
    GRABCO, D.; PRISACARU, A.; SHIKIMAKA, O.; HAREA, E.; PYRTSAC, C.; BRANISHTE, T. (Tehnica UTM, 2014)
    In this paper we developed mechano-chemical methods of structuring the surface of crystals Si (100) for use as substrates for solar cells. It was found that from all studied mechanical methods the 'scratching' one is more ...
  • Nano- and microscratching as a potential method for texturing the Si surface 
    PRISACARU, A.; SHIKIMAKA, O.; HAREA, E.; BURLACU, A.; ENACHI, M.; BRANISTE, T. (Academy of Sciences of Moldova, 2014)
    The possibility of Si texturing through the use of nano- and microscratching with subsequent chemical etching has been investigated. The influence of the scratching speed, orientation of the indenter (face-on, edge-on) and ...
  • Optical properties and photoconductivity of amorphous As2Se3:Sn thin films 
    HAREA, D. V.; IOVU, M. S.; COLOMEICO, E. P.; COJOCARU, I. A.; HAREA, E.; IOVU, M. A. (Technical University of Moldova, 2011)
    From scientific point of view, because the composition of chalcogenide glass (ChG) determine the kind of structural units and the mean coordination number, in the present work the amorphous films of the As2Se3:Sny (y=0÷10.0 ...
  • Physical and optical properties of amorphous (As2(Sb2)Se3)1-X:SnX thin films 
    IOVU, M. S.; HAREA, D. V.; COLOMEICO, E. P.; HAREA, E.; COJOCARU, I. A. (Technical University of Moldova, 2012)
    The mechanical properties (the hardness H), the morphology, the 119Sn Mossbauer spectroscopy, and the Temperature Modulated Differential Scanning Calorimetry (MDSC) of amorphous (As2Se3)1-x:Snx and (Sb2Se3)1-x:Snx bulk ...
