Fabrication of superconducting bilayer YBa2Cu3O7-delta (YBCO) thin film structure by Si ion implantation and properties of microbridge patterned on that are presented. YBCO thin film of 150 nm thickness was grown on single crystal (100) SrTiO3 substrate by inverted cylindrical magnetron sputtering. The sample was implanted with 100 keV, 1 X 10(16) Si ions/cm(2). Upon implantation with Si, the sample lost its electrical conductivity and diamagnetism while its crystalline structure was preserved after the annealing of the sample. The implanted ions do not alter the overall crystal structure of high temperature superconductor film. This allows the growth of epitaxial superconducting second layer YBCO film on top of the implanted area without using any buffer layer, thus providing an effective method of fabricating multilayer structures. The second layer film and the microbridge patterned by laser writing technique, showed the superconducting properties similar to those of pure YBCO base layer with a reduced critical current density.

Electrical and dielectrical properties of tantalum oxide films grown by Nd:YAG laser assisted oxidation
AYGÜN ÖZYÜZER, GÜLNUR; Turan, Raşit (Elsevier BV, 2008-11-28)
Tantalum pentoxide (Ta(2)O(5)) thin films (20 to 44 nm) have been grown by 1064 nm Nd:YAG laser oxidation of Ta deposited films with various thickness on Si. Fourier Transform Infrared (FTIR) spectrum, thickness distribution, dielectric and electrical properties of laser grown oxide layers have been studied. The effect of the sputtered Ta film thickness, laser beam energy density and the substrate temperature on the final Ta(2)O(5) film structure has been determined. It is shown that the oxide layers obtain...
Thickness and optical constant distributions of PECVD a-SiCx : H thin films along electrode radial direction
Akaoglu, B; Atilgan, I; Katircioglu, B (Elsevier BV, 2003-08-01)
Two sets of hydrogenated amorphous silicon carbide (a-SiCx:H) thin films were grown on glass and c-Si substrates by Plasma enhanced chemical vapor deposition (PECVD) technique at pressures of 0.5 and 0.1 Torr. The influence of the pressure on the distribution of thicknesses, refractive indices at 632.8 nm and optical gaps from the edge to the center of the bottom electrode of PECVD system is examined by transmission, single wavelength ellipsometry and Fourier transform infrared spectroscopy. A recently intr...
Structural and optical properties of thermally annealed thallium indium disulfide thin films
Guler, I; Hasanlı, Nızamı (Elsevier BV, 2020-06-30)
Structural and optical properties of thallium indium disulfide (TlInS2) thin films, deposited by thermal evaporation technique and thermally annealed at different temperatures, were analyzed. Crystallite size, dislocation density and lattice strain of the thin films were found from X-ray diffraction experiments. The atomic compositions of the films were determined from energy dispersive spectroscopy analysis. Surface morphology of the films was analyzed using atomic force microscopy. From room temperature t...
Frequency dependence of conductivity in intrinsic amorphous silicon carbide film, assessed through admittance measurement of metal insulator semiconductor structure
Ozdemir, O; Atilgan, I; Akaoglu, B; Sel, K; Katircioglu, B (Elsevier BV, 2006-02-21)
A slightly carbon rich hydrogenated amorphous silicon carbide (a-SiCx:H) film was deposited by 13.56 MHz plasma enhanced chemical vapor deposition technique on p-type silicon (p-Si) wafer. Admittance analyses of the metal-insulator-semiconductor device (Al/a-SiCx:H/p-Si)from strong accumulation to strong inversion gate bias were achieved within a widespread frequency range (10(1)-10(6) Hz). An adequate equivalent circuit for each bias regime was proposed. The dependence of the ac conductivity both under str...
Effects of boron doping on solid phase crystallization of in situ doped amorphous Silicon thin films prepared by electron beam evaporation
Sedani, Salar H.; Yasar, Ozlen F.; Karaman, Mehmet; Turan, Raşit (Elsevier BV, 2020-01-31)
In this work, we studied solid-phase crystallization of boron-doped non-hydrogenated amorphous Si films fabricated by electron beam evaporation equipped with effusion cells (e-Beam EC) on silicon nitride coated glass substrates. We investigated the effect of boron doping on the crystallization kinetics through a series of experiments with different boron doping concentrations controlled by the effusion cell temperature. We employed Raman spectroscopy, time-of-flight secondary ion mass spectroscopy, grazing ...
