ABSTRACT
Epitaxially grown SrTiO[sub 3] thin films with single-crystal-like dielectric behavior were obtained by the chemical mechanical planarization method. A parallel capacitor of a SrTiO[sub 3] film with excellent insulation was fabricated between YBa[sub 2]Cu[sub 3]O[sub 7-δ] electrodes by pulsed laser deposition. Dielectric constants of the parallel capacitor with a thickness of 300–600 nm are 330 and >20 000 at room temperature and 4.2 K, respectively, and obey the Curie–Weiss law above 150 K, being identical to the behavior of SrTiO[sub 3] single crystals. The microshort-free insulating film may aid in the development of oxide superconductor multilayer devices, such as superconducting quantum interference devices, three-terminal transistors, and field effect transistors. © 2003 American Institute of Physics.

    The growth of ultrathin (1.7-7.3 nm)YBa[sub 2]Cu[sub 3]O[sub 7-x] films on the SrTiO[sub 3](100) substrate is investigated by the mean-energy ion scattering technique. It is found that the growth of islands proceeds according to the two-dimensional and three-dimensional models and depends on the...

    Using an inductively coupled rf plasma operated at atmospheric pressure, superconducting thin films of Y1Ba2Cu3O7-x have been grown in situ on single-crystal yttria-stabilized zirconia [100] from an aerosol precursor. X-ray diffraction and rocking curve results indicate that the films are highly...

    We have studied the effect of varying the postdeposition anneal conditions on the properties of thin films of YBa2Cu3O7 prepared by coevaporation from Y, Cu, and BaF2. The temperature of this processing step determines both the microstructure of the films and the constituent phases. At low...

    We have grown superconducting films on the technologically important sapphire substrates by CO2 pulsed laser ablation from fully superconducting targets of Bi2Sr3-xCaxCu2Oy followed by appropriate post-annealing. The composition of the films was found to deviate slightly from the target....

    We have used x-ray photoemission spectroscopy to study the core level spectra of 200 Å Bi-Sr-Ca-Cu oxide thin films, in the hope that the importance of the surface sensitivity of photoemission is minimized for these samples, whose thickness is only 6–7 unit cells. The samples were...

    We compare the superlattice modulation, microstructure, and epitaxy of Tl2Ba2Ca2Cu3O10 thin films grown on MgO [100] and SrTiO3 [100] substrates by dc diode sputtering. Films grown on MgO were found to be quite clean with the c axis perpendicular to the substrate. However, no in-plane...

    We studied the composition dependence of high Tc phase Bi2Sr2Ca2Cu3Ox formation in Pb-doped Bi system thin films.

    Using rf sputtering technique, thin films of near single phase Bi2Sr2Ca2Cu3Ox were successfully prepared on SrTiO3(100), MgO(100), and LaAlO3(012) substrates. Zero resistance of these films occurred in the range of 90–105 K.

    A method is described for fabricating superconducting weak links in thin films of YBa2Cu3O7-x grown in situ by laser deposition. Carefully controlled electrical pulses applied to patterned bridges at 77 K are shown to reduce the critical current from initial values of typically 10 mA to values...
