Outline of Research at the Start

近年、様々な分野において円偏光光源の必要性が急速に高まっている。しかしながら、既存技術による円偏光発光（右回り・左回り）の電気的な制御は極めて困難であり、円偏光を用いた次世代技術の可能性を大幅に狭めている。本研究は、全く新しい原理を用いた 室温における電流励起円偏光発光素子と、その電気的な偏光方向の切り替えの実現に挑戦する。

Outline of Annual Research Achievements

2024年度は、本研究課題の最終目標である「室温における純粋円偏光発光とその電気的制御」の実現に向けて、特に「より高強度な電場の導入」と「高密度なキャリアドーピング」の２点に重点的に取り組んだ。これまでの研究では、低温環境下において電解質を凍結させることで酸化還元反応を抑制し、高電圧印加および高密度キャリア注入を可能にしてきたが、本年度は、常温で固体状態を保つ高融点電解質を新たに導入することで、冷却を必要とせず、化学的に安定かつ高耐圧な電解質環境の構築に成功した。加えて、この電解質に対してイオンの応答時間よりも十分に短いパルス電圧を印加することで、イオンの移動を抑制し、電極界面での電気化学的酸化還元反応を誘発することなく、従来の電位窓を大幅に超える強電場を安定的に導入する手法を確立した。この手法により、室温条件下で1 MA/cm2を超える大電流密度のキャリア注入を実現し、原子層材料中における励起子の極めて高密度な生成と、それに起因する非線形的な発光応答の顕著な発現を確認した。これらの成果は、レーザー発振に必要不可欠な反転分布形成に向けての技術的なブレイクスルーであり、本研究の最終目的に対して大きな前進を示すものである。また、本年度に確立された固体電解質と高速パルス電圧の組み合わせによる強電場導入技術は、冷却を伴わず、構造的・環境的安定性にも優れる点で極めて実用性が高く、今後の光・電子機能デバイス、特にフレキシブルエレクトロニクスや次世代オプトエレクトロニクス分野への応用展開が強く期待される汎用的基盤技術として位置づけられる。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

本研究において中核をなす「より高強度な電場の導入」および「高密度なキャリアドーピング」の２項目については、固体電解質と高速パルス電圧の組み合わせにより、室温での大電流密度注入に成功し、当初の計画を大きく上回る進展が得られている。一方で、「円偏光発光の純度向上」に関しては、理論予測に反して予期しない効果が影響していることが明らかとなり、現時点で高偏極率の実現には至っていない。これは当初想定していなかった課題ではあるが、研究全体としては計画通りに進捗しており、目標達成に向けた実験的・理論的検証を継続している。

Strategy for Future Research Activity

これまでに確立した高融点固体電解質と高速パルス電圧の組み合わせによる強電場印加・高密度キャリア注入手法を活用し、円偏光発光の高偏極率化に向けた取り組みを重点的に進める。具体的には、円偏光純度に影響を与えていると考えられる未解明の緩和過程や対称性破れ要因を系統的に実験・理論の両面から解析する。また、結晶方位や歪みの空間分布の最適化を通じて、バレー選択性を高める工夫を講じる。さらに、発光特性の詳細評価と同時に、共鳴構造や選択的励起条件の導入も検討し、室温における電気的制御可能な高純度円偏光発光の実現を目指す。
