ABSTRACT:
A superconductor-insulator-superconductor Josephson tunnel junction, comprising: a single crystalline substrate having a perovskite crystal structure; a template layer formed of a b-axis oriented PBCO thin film on the substrate; and a trilayer structure consisting of a lower electrode, a barrier layer and an upper electrode, which serve as a superconductor, an insulator and a superconductor, respectively, the lower electrode and the upper electrode each being formed of an a-axis oriented YBCO superconducting thin film and having an oblique junction edge at an angle of 30.degree. to 70.degree., the barrier layer being formed of an insulating thin film between the two superconducting electrodes, can be operated at a low power with an exceptional speed in calculation and data processing.
