  • Absorption edge of nanocrystalline cubic silicon carbide films 
    Lopin, A.V.; Semenov, A.V.; Puzikov, V.M.; Skorik, S.N. (Functional Materials, 2009)
    The optical absorption edge of nanocrystalline films of cubic silicon carbide polytype (nc-SlC) obtained by direct ion deposition have been studied using optical spectroscopy. Within the 1.12-6.5 eV, three optical absorption ...
  • Effect of silver on thermal e.m.f and electric resistance of La-Sr-Co-O ceramics 
    Kozlovskii, A.A.; Khirnyi, V.F.; Deineka, T.G.; Semenov, A.V.; Puzikov, V.M.; Mateychenko, P.V.; Finkel, V.A. (Functional Materials, 2008)
    The effect of silver on thermal e.m.f and electric resistance of La₁₋ₓSrₓCoO₃-δ (x=0; 0.15; 0.35) ceramic samples prepared by solid phase synthesis has been demonstated. The thermoelectric characteristics of the ceramics ...
  • Effect of tolerance factor and A-site cations disorderon transport properties of A’₁₋ₓA’’ₓCoO₃₋δ perovskites (A’ = Ho, Er; A’’ = Ca, Sr) 
    Kozlovskii, A.A.; Khirnyi, V.F.; Semenov, A.V.; Puzikov, V.M.; Deineka, T.G.; Gaiduk, O.V.; Chiang, Yu.N. (Functional Materials, 2009)
    Temperature dependences of conductivity for Ho₁₋ₓSrₓCoO₃₋δ, Er₁₋ₓSrₓCoO₃₋δ, Ho₁₋ₓCaₓCoO₃₋δ and Er₁₋ₓCaₓCoO₃₋δ (x ~ 0.15, 0.25, 0.35, 0.45, 0.55, 0.65, 0.75, 0.85, 0.95) having the ABO₃ perovskite structure have been studied ...
  • Gap symmetry and charge density excitations in high-Tc superconductors with extended saddle points in electron spectrum 
    Pashitskii, E.A.; Pentegov, V.I.; Semenov, A.V. (Condensed Matter Physics, 1999)
    It is shown that the strong anisotropy of the one-particle electron spectrum, due to the presence of extended saddle-point features (ESPF) close to the Fermi level in the hole-type cuprates YBCO and BSCCO, leads to the ...
  • Ion plasma deposition and optical properties of SiC films 
    Semenov, A.V.; Lopin, A.V.; Puzikov, V.M.; Muto, Sh. (Functional Materials, 2005)
    SiC films have been obtained by direct deposition from a C and Si ions flow at energy values in the 30 to 1.500 eV range. The films deposited at the substrate temperature 600 С were chemically and structurally disordered. ...
  • Optical properties of silicon carbide obtained by direct ion deposition 
    Lopin, A.V.; Semenov, A.V.; Puzikov, V.M.; Trushkovsky, A.G. (Functional Materials, 2006)
    Optical transmission, absorption and reflection spectra of silicon carbide thin films deposited on sapphire substrate from the carbon and silicon ionic flows have been investigated. The films have been obtained at various ...
  • Photovoltaic effect in p–SiC/p–Si heterojunction 
    Kozlovskyi, A.A.; Semenov, A.V.; Puzikov, V.M. (Functional Materials, 2013)
    The photovoltaic effect of isotype heterojunction with hole conductivity formed films of nanocrystallinep–21R–SiC, deposited on single-crystal substrate of p–Si, has been studied (heterojunction p–SiC/p–Si). The films were ...
