PURPOSE:To produce a Bi-Sr-Ca-Cu-O superconducting thin film with the (110) face selectively grown and oriented with respect to the substrate surface and appropriate to prepare the Josephson junction device, three-terminal device, etc. CONSTITUTION:A Bi-Sr-Ca-Cu-O superconducting thin film is formed on a substrate consisting of an MgO [110] single crystal by chemical vapor deposition, and the (110) face is selectively grown with respect to the substrate surface. Consequently, Bi-Sr-Ca-Cu-O superconducting thin film extremely effective for the Josephson junction device, three-terminal device, etc., is obtained by chemical vapor deposition. |
