  • Back surface reflector optimization for thin single crystalline silicon solar cells 
    Kopach, V.R.; Kirichenko, M.V.; Shramko, S.V.; Zaitsev, R.V.; Tymchuk, I.T.; Antonova, V.A.; Listratenko, A.M. (Functional Materials, 2007)
    It has been shown that for single crystalline silicon solar cells (Si-SC) with 180-200 μm thick base crystals, the optimum back surface reflector (BSR) is TiO₂/Al with 0.18 μm thick oxide layer. At such BSR, the reflection ...
  • Biphasic (HA/β-TCP) calcium phosphate ceramics 
    Zyman, Z.Z.; Tkachenko, N.V.; Polevodin, D.V. (Functional Materials, 2007)
    A new manufacturing technique for dense and porous biphasic calcium phosphate (BCP) ceramics of hydroxyapatite HA/I3-tricalcium phosphate (β-TCP) composition has been proposed. The idea consisted in the combination of ...
  • Effect of growth atmosphere on Ce³⁺ incorporation in Gd₂SiO₅ single crystals 
    Bondar, V.G.; Krivoshein, V.I.; Martynov, V.P.; Nagornaya, L.L.; Sideletskiy, O.Ts. (Functional Materials, 2007)
    Peculiarities of oxide crystal growth by the Czochralski technique have been discussed in the present paper. A correlation between oxygen content in the growth atmosphere and the Ce³⁺ incorporation coefficient at growing ...
  • Nanoscale Co/C multilayers for "carbon window" Schwarzchild objective 
    Bugayev, Ye.A.; Devizenko, A.Yu.; Zubarev, E.N.; Kondratenko, V.V. (Functional Materials, 2007)
    The formation features of the Co/C multilayer with ≈2.3 nm period have been studied with aim to form a Schwarzschild objective on a "carbon window" for medical and biological investigations. A sequence of multilayer ...
  • New approach to catalytic Co-W alloy electodeposition 
    Ved, M.; Shtefan, V.; Bairachnaya, T.; Sakhnenko, N. (Functional Materials, 2007)
    The pulse electolysis parameters (current density amplitude, frequency and on/off time ratio of pulses, pause and pulse duration) influence on cobalt-tungsten alloy deposition has been revealed. The alloy electodeposition ...
  • Optical properties of LiNbO₃:Zn and LiNbO₃:Zn:Nd fiber single crystals grown by micro-pulling down method 
    H.J. Lee; J.W. Shur; O. Nakamura; D.H. Yoon (Functional Materials, 2007)
    The present interest in small compact diode pumped lasers has supported research on new solid state laser systems based on non-linear crystals. High quality LiNbO₃ fiber single crystals were grown by micro-pulling down ...
  • Potentialities for sapphire strength enhancement 
    Voloshyn, O.V.; Lytvynov, L.A.; Slyunin, E.V. (Functional Materials, 2007)
    The study results are presented concerning the influence of technological factors, such as annealing atmosphere and mechanical treatment, on the sapphire strength. The ultimate strength under four-point flexure has been ...
  • Production of nano-pore track membranes based on PET films irradiated by Ar ions 
    Bomko, V.A.; Burban, A.F.; Kobets, A.F.; Kryshtal, A.; Vorobyova, I.V.; Zaitsev, B.V. (Functional Materials, 2007)
    Changes in diameters and depths of pores were studied in the process of etching polyethyleneterephthalate films irradiated with Ar ions having the energy of 1 MeV/n. Information about the pore diameters and lengths was ...
  • Structure perfection of bulk and near-surface layers in sapphire single crystals 
    Tkachenko, V.F.; Puzikov, V.M.; Dan`ko, A.Ya.; Budnikov, A.T.; Lukienko, O.A. (Functional Materials, 2007)
    Triple-crystal X-ray diffractometry has been used to study the structure perfection in bulk and surface layer of basal-oriented sapphire single crystals grown using horizontal directional crystallization (HDC) in reducing ...
  • Thermal lag of the growth furnace heating assembly at CsI(Na) crystal growing fron constant melt volume on a seed 
    Goriletsky, V.I.; Vasilyev, V.V.; Sidletskiy, O.Ts.; Tymoshenko, M.M.; Sumin, V.I. (Functional Materials, 2007)
    Thermal lag of the heater - crucible - crystal system has been determined at a large size CsI(Na) single crystal growing from constant melt volume on a seed. It has been established that during radial growth the temperature ...
