Outline of Final Research Achievements

We have successfully fabricated a single-crystal bismuth nanowire with several-ten- to several-hundred-nm diameter and more than 1mm-length embedded in a quartz template. And a technique using nano-fabrication has also been developed to make local electrodes at the side and edge of the nanowire. So, we can measure the transport coefficients of the nanowire like resistivity, Seebeck coefficient, and Hall coefficient. We will indicate the giant Seebeck coefficient from experimental results using the four-probe method.

Academic Significance and Societal Importance of the Research Achievements

有効質量が小さなBi材料を採用したナノワイヤーでは、ワイヤー直径100nm以下で量子効果の導入が確実視されている。しかし確度の高いゼーベック係数測定のためには、ミリスケール長さを実現する必要があり、巨大ゼーベック効果を実証する1次元量子ナノワイヤー熱電変換素子の作製ならびにその物性測定の困難さに直面している。また量子効果を基にした理論モデル提唱から25年経過した現在、実験的なアプローチから巨大ゼーベック効果実証が学術的に問われている。
