Outline of Research at the Start

高い元素選択性(A=Sn,Pb,Bi,Y,La-Lu M=Nb,Ta,Ti,Cr,V X=S,Se)を有するAXおよびMX2層それぞれの機能を合わせ持つ三元系層状カルコゲナイドAMX3単結晶の育成手法を確立し, AXとMX2層を自在に組み合わせることで, 新たな機能の創出を目指す.

Outline of Final Research Achievements

Nb-Bi-Se, Nb-Sn-Se-based misfit-layered compounds single crystals have been successfully grown using alkali metal chloride. Those grown single crystals were evaluated to the physical properties which were mainly superconductivity and tunneling spectroscopy. Additionally, multi-layered Nb-Bi-Se, Nb-Sn-Se-based compounds bulk single crystals were obtained, which were observed to become superconductivity.

Academic Significance and Societal Importance of the Research Achievements

層状構造を有する化合物において, 様々な機能が報告されている. その一つに低温で見られる超伝導現象があり, それが起こる臨界温度は, 総じて層状化合物で高い. 高い臨界温度(特に室温)を有する超伝導体の発見は, 損失のない電力送電を可能にするなど社会的なインパクトは大きい. そういった状況の中, 本研究では, 層状化合物の一つであるミスフィット層状化合物に着目し, その単結晶育成と超伝導特性について研究を行った. これは, 高い臨界温度の起源をあきらかにするといった目的の研究の一つとして行った. また, ミスフィット層状化合物における新たな機能の探索も焦点に研究を行った.
