Outline of Final Research Achievements

In this study, a custom-designed ultra-high vacuum sputter system was set up to adapt metallic glasses to physical vapor deposition onto low vapor pressure liquids. As a result, challenges such as target limitations due to the specifications of the ion coater were solved, and optimization of sputtering conditions on fabricating and dispersing nanoparticles/wires of multi-component amorphous alloys can be enabled. As a secondary result, we have demonstrated the electric field induced diffusion/aggregation model for guided self-assembly phenomena in surface adsorbed molecular systems.

Academic Significance and Societal Importance of the Research Achievements

本研究で取り組んできたアモルファス合金のナノスケール構造体は、ナノ化学分野においてはアモルファス合金という新素材への挑戦となり、アモルファス材料工学分野においてはビルドアップ法によるナノ化という新機軸の提起となる。
表面吸着分子系において得られた誘導自己組織化現象に関する基礎的知見は、アモルファス合金ナノ構造体を分散安定化させた流体試料を外場によって制御し、階層構造・配向構造を形成する技術の構築に繋がると考える。
