Outline of Final Research Achievements

Aim of this study is to improve efficiency of thermoelectric conversion by thermoelectric material like bismuth which is one of most material. A strategy has been introduced into the material using nano-wire geometry with nano-scale diameter and milli-scale length, making it possible to occur quantum effect like one-dimensional density of state to enhance its performance; however, the handling of the nanowire has been quite difficult due to its size and fragile. In addition, several local electrodes are required to measure its properties. We have employed nano-fabrication technique we have proposed and have successfully fabricated the electrodes for the measurement. Finally, the measurements of resistivity, magneto-resistivity, and Hall coefficient were performed simultaneously. The experimental results showed us that the mobility suppression in low temperature region was derived from the limitation of the mean free path of the carrier.

Academic Significance and Societal Importance of the Research Achievements

超低炭素社会・省資源社会を目指したクリーンエネルギー需要が高まっている中、熱(温度差)から電気への直接エネルギー変換を可能にする熱電変換現象に着目している。資源の乏しい日本にとって、二酸化炭素を輩出しないエネルギー創成研究は重要であることは知られているものの、熱電変換によるエネルギー変換効率は10%以下と小さい。本研究では、材料をナノスケールにすることで採り入れることが出来る量子効果に着目し、エネルギー変換効率の向上を目指している。
