空間秩序研究チーム

空間秩序研究チームは、「ピコ秒レベルの時間領域において、電子の空間分布及び空間秩序をナノメートル空間スケールで実空間イメージングすることによる、先端材料の機能発現機構の解明」を目指しています。本研究目的を達成するために、SPring-8放射光における、40ピコ秒時間分解能におよぶ超短パルス特性と高輝度性を最大限に利用可能な量子空間秩序計測システムの開発も行います。また、他の2つのチームとの有機的な共同研究により、電子のスピン秩序、励起秩序と空間秩序の三局面から機能空間と導入された分子の相互作用について解明し、放射光を用いた量子秩序研究の物質科学、特にボトムアップ材料設計への道を開拓することを目指します。

研究テーマ

• ナノ空間における電子秩序ダイナミクスの研究
• 外場応答型機能性配位高分子の研究
