抄録

A high-Tc superconducting (HTSC) thin film with single crystal quality and atomically flat surface is a basic requirement for the fabrication of HTSC electronic devices. Despite extensive effort since the discovery of high-Tc superconductivity, this requirement has not been fully satisfied yet. Based on our experience on HTSC thin film growth, we proposed a novel fabricating method of single crystal RBa<SUB>2</SUB>Cu<SUB>3</SUB>O<SUB>7−δ</SUB>(R=Y, Nd) thin films that are free from grain boundaries and have atomic scale surface smoothness. This method was devised in view of the thermodynamic phase diagram of RBa<SUB>2</SUB>Cu<SUB>3</SUB>O<SUB>7−δ</SUB> and the characteristics of vapor phase epitaxy (VPE). Since gas, liquid and solid phases are involved in this film growth, it is denoted Tri-Phase Epitaxy(TPE). Giant single crystal grains, verified by X-ray diffraction and transmission electron microscopy (TEM), should provide a big advantage for the use of these films in such applications as high frequency transmission lines and superconducting tunnel junctions.
