Superconducting Electronics Group
Group Outline and Primary Goal
Superconducting Electronics group promotes the research and development of new superconductors, the elucidation of the mechanism of high-Tc superconductivity through both theoretical and experimental approaches, and application technologies for superconducting devices and new technologies for their realization. We also pursue the research and development for the industrial applications of superconductors.
Key Themes of Research
- Development of superconducting materials that have higher Tc, or possess other interesting or useful properties
- Design and trial production of copper oxide high temperature superconducting cables for industrial applications
- Development of basic technology for industrial use of iron-based high-temperature superconducting materials
- Elucidation of the mechanism of superconductivity in high-temperature superconductors represented by copper oxide and iron compound superconductors
- Research for the development of new functional substances and new devices, and development of physical property evaluation methods
