Abstract
Description
Superconductor Research Progress, Ed.: Li-Chun Liang, S53 - 92, Nova Science Publ. (2008), ISBN: 978-1-60456-083-1)、又は完全なエピタキシ配向から或る程度の食い違いで、スライス及び研磨された基板上におけるエピタキシャル成長により(Appl. Phys. Lett. 86 (19) (2005) 192507, IEEE Trans. Appl. Supercond. 17, (2007), 3459 - 3462)実現することができる。後者は、結晶軸(c軸)が典型的には基板垂線から約1°〜6°ずれることを意味する。そのようにすることにより、サファイヤ上に亀裂のないYBa2Cu3O7層を1μmまでの厚さで作製することが可能となった。しかしながら、多孔性は電流密度の損失にもつながるので、差し引きの後、伝送電流の改善のみが観察された。
