On nontextured substrates, YBCO superconducting thick films were fabricated using a simple screen-printing method, from Cu-free powders (Y2O3 and BaCO3). However, the films have poor superconducting properties, such as the critical current density, Jc value due to the random orientation of the films. In this work, we investigate the influence of substrate texture on superconducting properties of the film. The films screen-printed on the nontextured and textured Cu substrates were heat-treated by 2-step procedure in air (980 °C 10 sec + 930 °C 90 sec) followed by oxygen annealing at 450 °C for 1 hr. We speculate that Cu ions diffusion from the textured Cu substrates is still faster than Cu ions diffusion from the nontextured Cu substrates that CuO formed excessively in the film deteriorates superconducting properties of the YBCO film.

The growth morphology and interface structure of Nd1.85Ce0.15CuO4−y (NCCO) films grown by pulsed laser deposition on two different types of substrates, “perovskite” LaAlO3 (LAO) and SrTiO3 (STO) and “fluorite” Y2O3-stabilized ZrO2 (YSZ), were studied using cross-sectional electron microscopy. Structurally, the NCCO films are different when grown on the two types of substrates in three aspects: (i) epitaxy, (ii) substrate-film intermixing, and (iii) substrate-film interface roughness. In general, films deposited on “fluorite” substrates showed better superconducting properties than the films grown on “perovskite” substrates, especially for thinner films. Lattice mismatch considerations are not sufficient to explain the observed differences since films grown on the YSZ substrate showed sharp substrate-film interface in spite of their large lattice misfit. The atomic arrangements at the interface were analyzed in terms of electrostatic energy (charge balance) and matching of the oxygen sublattices in order to account for the experimental results.
