    Notes: Two all-organic complexes, MC+TCNQ and BBDN+TCNQ, with electrical bistable states at room temperature have been discovered. The resistivity of these thin films prepared in vacuum can be transferred from high to low under a voltage of few volts. The transition time is 〈100 ns. Therefore, both materials are suitable for making write-once read-only memories. © 1995 American Institute of Physics.

    Notes: Abstract Bi-based superconductors are of great interest in high-temperature superconductors. We describe what is believed to be the first synthesis of these materials using the Pechini process, a low-temperature synthetic method that often yields inorganic oxide of excellent phase purity and well-controlled stoichiometry. Using this process, it has been possible to synthesize phase-pure Bi-2223 phase by calcining the appropriate polymeric precursors in air at 800°C for several hours. The superconductivity studies show that the Pechini-synthesized materials appear to offer high-quality performance.

    Influence of deposition temperature on the superconductivity of Y1−x HoxBa2Cu3O7 −δfilms produced by dc-magnetron sputtering (1996)

    Notes: Abstract Experimental results of research on the influence of deposition temperature (T s) on crystal structure and superconductivity of Y1−x HoxBa2Cu3O7 −δ (YHBCO) films deposited by dcmagnetron sputtering are reported. X-ray diffraction analysis showed that the films grew with preferential orientation of thec-axis normal to the substrate surface in the range of temperature 750–820°C. The single-crystal structure of the YHBCO films grown epitaxially at the optimal substrate temperatures of 820, 800, 760, and 750°C, respectively, have been established by rocking curves, Φ-scan, and electron channeling pattern (ECP). Typical values of the critical current density (A · cm−2) at 77 K and 0.1 T field are 2.1×105, 4×105, 6.2×105, and 3.1×105 for thex=0, 0.2, 0.4, 0.7 films respectively, measured by a Quantum Design magnetrometer (H∥c).

    Critical current density and flux pinning in Y1−x Ho x Ba2Cu3O7−δ epitaxial films (1996)

    Notes: Abstract The critical current densityJ c of Y1−x Ho x Ba2Cu3O7−δ (YHBCO) epitaxial thin films withx=0, 0.2, 0.4, 0.7 at various temperatures and magnetic fields has been measured magnetically. TheJ c and flux pinning density Fp values are significantly enhanced with the Ho substitute amountx with the optimal effect achieved at Ho concentration around x=0.4 in the entire measured temperature (30–77 K) and magnetic field (0–3 T) ranges. X-ray diffraction patterns have shown that the greater the lattice deformation, the higher theJ c of the films.

    Mechanism of RF plasma induced fragmentation of SiCl4 and surface functionalization of polymeric substrates from SiClx species (1996)

    Notes: The generation of extremely reactive species of silylium (silicenium) ions under plasma conditions opens up new ways for surface modification, even of the most inert polymeric surfaces. To control the plasma-induced chemistry and to tailor new molecular surface architecture, the mechanism of formation of the active species of the discharge must be understood. In this work the plasma-induced molecular fragmentation of SiCl4 was studied and the surface functionalization of cellulose paper (CP), polyester (PET), polypropylene (PP), and polytetrafluoroethylene (PTFE) substrates with silicon atom based active species was evaluated. Gas chromatograph mass spectroscopy (GC-MS) and low Energy Electron MS (LEEMS) measurements carried out both on SiCl4 and on the molecular mixture resulting from the recombination of plasma generated species indicate that the most predominant fragments are SiCl3+ cations accompanied by SiCl2+ and SiCl+ species. Survey and high-resolution electron spectroscopy for chemical analysis (ESCA) data collected from plasma functionalized surfaces show significant silicon and oxygen atom content regardless of the nature of the substrates. © 1996 John Wiley & Sons, Inc.
