| Outline of Final Research Achievements |
We prepared Bi-based oxide superconductor films on single crystal substrates of low dielectric constant targeting fabrication of high-power terahertz devices. We used our originally developed MOCVD apparatus. The as-obtained films were characterized in detail from the structural viewpoint. In this respect, we developed and applied a new X-ray diffraction method. We found that our films are of high-quality, twin-free single crystal non-c-axis oriented epitaxial films. Some films were with the c-axis inclined approximately 45 degrees to the surface of the substrate. In other cases, we have grown a-axis oriented films. To our knowledge, the growth of a-axis oriented Bi-2223 thin films is demonstrated for the first time.
The non-c-axis and a-axis oriented films enable fabrication of novel device structures expected to be the epoch-making high-power THz devices. The long awaited break through is focused especially on the coherent THz emission devices.
