Liquid phase epitaxy has been used to grow high-temperature superconductor thick films for high Jc applications. Growth on single crystal substrates has so far produced very encouraging results. YBa2Cu3O7-δ films with thickness up to 10 μm can be grown at a typical rate of 1 μm/min, with excellent in-plane texture and 100% density. Tc values of 91 K and Jc values over 1 × 106 A/cm3 (77 K, O T) have been achieved. More effort is necessary to grow REBa2Cu3O7-δ (RE=rare earth) thick films on metallic substrates.
