Abstract:The study of processing by liquid-phase epitaxy (LPE) is promising because the LPE process can provide rapid and thick film formation of RBa2Cu3O7-(RBCO). The growth rate can reach 10 m min-1and films of more than 5 m in thickness formed by the LPE process show a high critical current density of about 1 MA cm-2. To apply this process widely, a decrease of the processing temperature is required because it gives rise to a reaction between the solution and many of the substrate materials. Film formation on yttria-stabilized ZrO2and silver substrates, which are more reactive than other materials such as MgO or SrTiO3, has been achieved by decreasing the temperature to below 920 °C, with the addition of BaF2in the solution. This paper describes processing by LPE for forming RBCO films and efforts for practical application towards coated conductors and RF electronic devices.
