Outline of Final Research Achievements

Layered mixed anion compounds, such as LaOBiS2, have been intensively studied since they have high flexibility for designing properties by changing composed anions. The aims of this research are 1) control properties by tuning chemical bond between Bi and S/Se and 2)producing new two-dimensional nanosheets by exfoliation. Research accomplishment includes the correlation between rare earth elements and superconductive transition, and the relationship between chemical pressure of the chmical bond of Bi-S/Se and superconductive transition temperature. The synthesis of LaOBiS2 nanosheets have been successful. We discover new layered oxysulfides including antimony and indium.
