| Abstract(in English) | We have described our approach to the fabrication of high-Tc Josephson tunnel junction. We developed "temperature gradient method " to obtain high quality (smooth, high Tc, and crack free) a-axis oriented Yba_2Cu_3O_<7-δ> (YBCO) films by inserting a suitable buffer YBCO layer. Wet etching technique was developed to finish the SrTiO_3 substrate with an atomically smooth surface. This surface enabled us to perform perfect layer-by-layer growth of insulating oxides by laser MBE. Combining these techniques, we have fabricated S (superconducting)-I (insulating)-S structures and processed them into devices. The cross sectioned microstructure was examined for the specimens cross-sectioned by focused ion beam milling. The structures from atomic scale to device scale were elucidated to be consistent with those we have designed. |
