| Outline of Final Research Achievements |
The Josephson junction has been a subject of a large number of studies. Ordinary a Josephson junction basically consists of superconductor-insulator-superconductor (SIS) tunnel junctions. Al/AlOx/Al and Nb/AlOx/Nb Josephson junctions are generally used for superconducting application. On the other hand, various superconducting devices have been proposed. For example, there is an electric field-controlled Josephson junction. The device consists of a coplanar superconductor-semiconductor-superconductor Josephson junction with insulated gate formed over the semiconducting channel. We have fabricated the NbN/IZO/NbN junction and carried out electrical transport measurements/. Non-linear I-V characteristics appeared below 10K by superconductivity of NbN electrode and showed diode-like behavior.
