| Outline of Final Research Achievements |
With the hope of creating CuO-Ag nanostructure, sequence control of metal particle diffusion was developed. Firstly, annealing and voltage-stressing experiments were performed to fabricate CuO-Ag nanostructures by sequentially inducing stress migration with driving force of stress gradient and ionic migration with driving force of electrical potential gradient. Secondly, the sensitivity to humidity and heating properties of the nanostructured material was evaluated, which indicates the potential applications in the fields of humidity sensor and electrical heater.

本研究では微細複合構造体の新規創製を実現するために提案した異なる拡散現象の順序制御は、ストレスマイグレーションとイオンマイグレーションの先駆的な融合を図り、従来の化学的創製手法と異なり、化学薬品を一切使用することなく、簡易的なプロセスによるクリーンかつ革新的な手法である。またナノ構造体を付与した金属材料の湿度応答と発熱特性を評価することにより、湿度センサや発熱素子への応用可能性を示し、エレクトロニクス分野への展開にも資する。
