Outline of Research at the Start

Thermoelectric (TE) materials can convert directly waste heat to electrical energy in solid-state-device without any moving parts and carbon emissions. In this project, we will develop a comprehensive theory for TE, and expose new
concepts to improve TE performance of low-dimensional materials

Outline of Final Research Achievements

We theoretically studied the thermoelectric (TE) transports of two-dimensional materials and 3D topological semimetals. In the 2D materials, such as Janus γ-Ge2SSe, we found an intrinsic low lattice thermal conductivity of 3.33 W/mK at room temperature, contributing to high TE efficiency. We also found that the 3D semimetal can enhance the TE performance due to the unusual density of states of the 3D semimetals and shows a new TE response, the so-called TE Hall effect. As a related topic, we also discussed low-dimensional materials for another energy conversion, such as photocatalysis.

Academic Significance and Societal Importance of the Research Achievements

熱電材料は、排ガスを発生させることなく、廃熱からエネルギーを取り出すことができます。したがって、熱電変換デバイスは、カーボンニュートラルな社会にとって不可欠なエネルギー変換となる。本研究では、熱電材料として2次元材料と3次元半金属に注目した。その結果、単層2次元材料は、量子閉じ込め長によって熱電性能を向上させることができることを発見した。一方、3次元半導体は、そのトポロジー特性に基づき、熱電変換を実現する新しい方法を示しています。このように、今回の成果は、高性能なエネルギー変換を実現する新しい熱電材料の開発に貢献するものである。(Using DeepL Translator)
