Outline of Final Research Achievements

To clarify the superconducting properties and the mechanisms of superconductivity in the BiCh2-based (Ch: chalcogen) compounds, we have studied the physical properties and crystal structure of RE(O,F)BiCh2-type compounds. We revealed that the enhancement of in-plane chemical pressure should be essential for the induction of superconductivity and the increase of transition temperature (Tc) in the BiCh2-based superconductors.
New superconductors with a RE(O,F)BiCh2-type structure, new materials with SbS2-type layers, and a Sn1-xAgxTe superconductor, which may be related to topological superconductivity, were discovered during this project.
Furthermore, we have revealed that the Se-substituted LaOBiS2-xSex can be a promising thermoelectric material. The enhancement of in-plane chemical pressure by Se substitution resulted in large electron mobility without degradation of Seebeck coefficient; the highest dimensionless figure-of-merit (ZT) was 0.36 in LaOBiSSe.
