Outline of Research at the Start

原子オーダー低次元材料の熱物性データは数10%といった大きな誤差を含む場合が多く、欠陥と界面の影響についても調べる手法が限られている。そこで、温度分解能を既存手法より1-2桁向上させるとともに時間/空間分解能で10ps/10nmを実現することで、原子オーダー材料の熱物性の分布計測まで可能とする汎用プラットフォームを構築する。このプラットフォームに基づいて、熱輸送の波動的効果を上記の分布的探査によって解明することも目指す。これらの技術を駆使して、次世代電子機器に不可欠な低次元材料を対象として形状と不均質性の様子からホットスポットの予測と高度な熱制御を可能とするのが最終目標である。

Outline of Final Research Achievements

Throughout this project, we developed high-resolution thermal property measurement methods based on Raman spectroscopy and scanning electron microscopy. We improved the temperature resolution of Raman-based thermal measurements. We also developed a method to simultaneously measure the thermal conductivity and observe the internal structure of 1D materials and introduced electron-beam heating for high-resolution thermal resistance mapping. In addition, we successfully fabricated ultrafine nanostructures in graphene to study phonons’ wave behaviors.

Academic Significance and Societal Importance of the Research Achievements

本研究にて得られた成果は、ナノスケール熱物性の新たな計測方法を開発することで、熱物性分野の発展に貢献した。本研究で開発した熱計測法はナノスケール伝熱機構の解明への応用を期待でき、電子機器の高度な熱管理技術の開発および高度な情報化社会の達成へ貢献できる。
