Outline of Final Research Achievements

We have investigated chemical pressure effects on local structure, superconducting properties, and thermoelectric properties of BiCh2-based layered compounds. According to the obtained concept for BiCh2-based material design, new superconductors, (Eu,RE)FBi(S,Se)2, (La,Ce)OBiSSe, and (Ce,Pr)OBiS2, were discovered. Furthermore, La2O2Bi3AgS6 with a four-layer-type superconducting layer was discovered. From isotope effect, we found that BiCh2-based superconductors can be categorized into unconventional superconductors. We have also developed related layered compounds with InS2-type and SbSe2-type conducting layers.

Academic Significance and Societal Importance of the Research Achievements

本研究は2012年に研究代表者らが発見した層状超伝導体の発現機構解明および物性制御手法確立を目指した研究である.日本で発見された新機能性材料をさらに発展させるために,局所構造に着目した研究を展開した.得られた知見は今後の新層状機能性材料開発に有意義なものであると考えている.
また,本研究で得られた非従来型超伝導機構の可能性は,超伝導基礎研究の分野に新たな研究対象を提供することにつながるため,学術的意義も高いと考えている.
