Outline of Final Research Achievements

We fabricated self-assembled dots of CdTe containing a single atom of Cr and investigated the behaviors of single magnetic spin of Cr inside the dot. By observing the excitonic emission from an individual dot in the micro-photoluminescence measurement, we clarified various properties of the single Cr spin interaction with the exciton. We obtained new findings such as the splitting of the Cr spin state due to the lattice strain, the interaction with a hole, the relaxation process, the optical Stark effect.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果により、CdTe自己形成ドット中の単一Crスピンの種々の特性を明らかにすることができた。特に、ドット中のCrスピンが暗状態で比較的長いコヒーレンスを保つこと、また格子歪と強く結合していることが明らかになった。この成果は、単一スピンを用いたメモリや量子情報処理などへの応用の可能性を示したという点で学術的、社会的意義を有すると考えられ、今後の研究の発展に期待が持たれる。
