報(bào)告摘要：The REBCO superconductor is a key material for fundamental study on the copper oxide: its superconductivity mechanism and engineering application. The preparation of high quality epitaxial film is one of the most important fields for this material. Adopting liquid phase epitaxy (LPE), our research involves the growth of various orientated films and artificial film structures, for superconducting mechanism study, Josephson junction’s device design and artificial flux pinning optimization. Through the thermodynamics and kinetics tuning, we have realized the effective control in preparing the pure a- or c-axis oriented film; obtaining the high quality artificial a/c interface structure; growing the a-axis grains mixed c-axis oriented films with well alignment, which are unsuccessful by the prior art crystal growth methods.
