  • Method of forming high temperature superconducting Josephson junction
    Patent number: 6839578
    Abstract: A method of forming a novel high temperature superconducting Josephson junction which is capable of achieving a formation of a Josephson junction having high characteristics conveniently and quickly without necessitating costly micromachining facilities. Two high temperature superconducting whisker crystals are crossed with each other on a substrate and subjected to thermal treatment to form a Josephson junction between the two high temperature superconducting whisker crystals.
    Type: Grant
    Filed: June 9, 2003
    Date of Patent: January 4, 2005
    Assignee: National Institute for Materials Science
    Inventors: Yoshihiko Takano, Takeshi Hatano, Akira Ishii, Syunichi Arisawa, Kazumasa Togano
