Outline of Final Research Achievements

We propose a fabrication process for a single-crystalline boron-doped diamond Josephson junction with two different step structure and demonstrated the first operation of a single-crystalline boron-doped diamond SQUID operating above liquid helium temperature 4.2 K. Moreover, we have established nano- and micro-size patterning processes for superconducting boron-doped diamond films with low damage using selective microwave plasma chemical vapour deposition and selective oxygen plasma etching.

Academic Significance and Societal Importance of the Research Achievements

本研究成果である微細加工技術の確立と液体ヘリウム温度4.2K以上で動作する堅牢なダイヤモンドSQUIDの実現により、従来材料を凌駕する簡便で堅牢な超伝導デバイス応用にダイヤモンドが有用であることを証明した。また、ダイヤモンドは半導体として優れた性能を有しており、半導体と超伝導体の性質を融合した新規デバイスの創出が今後期待される。
