| Outline of Final Research Achievements |
The purpose of this research is to demonstrate quantum sensing using rare-earth ions (Nd and Pr ions) implanted into gallium nitride. First, the resonant excitation condition was clarified to excite Nd/Pr ions efficiently. To further enhance their photon emission, nanopillar structures (500 nm height) were formed on GaN surface and the photon emission from Pr ions implanted into the nanopillars was investigated. As a result, more than twentyfold enhancement was achieved when the pillar diameter was 200 nm. Also, measurement of local temperatures using RE ions was demonstrated and it was concluded that quantum sensing using single RE ion is feasible by improving the measurement system.

| Academic Significance and Societal Importance of the Research Achievements |
量子センサーは、原子1個の大きさで温度や磁場、電場といった外部環境を計測する「世界最小のセンサー」であり、生命科学研究やデバイス異常診断技術のブレイクスルーをもたらすものとして期待されている。しかし、量子センシングを実現できる系（材料）は限られていることが課題のひとつであった。今回の成果は、新たな系（窒化ガリウム中の希土類元素）での量子センシングを実現したものであり、量子センシングの可能性を拡げるとともに、近年開発が進められている窒化ガリウム半導体パワーデバイスの診断技術にも利用できる可能性がある。
