Outline of Final Research Achievements |
A new superconductor Cux(PbSe)5(Bi2Se3)6 is synthesized with the electrochemical method. The parent material (PbSe)5(Bi2Se3)6 is topological-insulator-related system, in which the topological insulator Bi2Se3 and ordinary insulator PbSe coexist in the unit cell. The transition temperature is not as high as CuxBi2Se3, but the superconducting volume fraction is almost 100% unlike CuxBi2Se3. This system is a candidate for a topological superconductor.
