Outline of Final Research Achievements

By using an anodic porous alumina as a starting material, fabrication of a coaxial nanocable array having single-nanometer-scale aperture was succeeded. The coaxial nanocable could efficiently propagate visible light. In addition to this, the coaxial nanocable could be applied to a nanometer-scale photochemical reaction field. The obtained coaxial nanocable is expected to be applied to not only the photochemical reaction fields but also nanolithography and ultra-high-density optical recording.

Academic Significance and Societal Importance of the Research Achievements

シングルナノメートルスケールの開口径を有する同軸ナノケーブルを作製し,光伝搬特性を実験的に評価した例はこれまでに報告がない.さらに本課題では,得られた同軸ナノケーブルを用いてナノメートルスケールの極微小な領域に光化学反応を誘起することにも初めて成功しており,本研究成果の学術的意義は高いものと考えられる.本同軸ナノケーブルは,応用性の広範さから,光学,生命科学,物性科学などナノ空間への光学的アプローチを必要とする様々な分野の基礎・応用研究に大きな波及効果をもたらすものと期待される.
