Despite the tremendous efforts in exploring topological superconductivity, its presence is however still under heavy debate. The Dirac electrons have been proven to exist on the surface of a topological insulator. It remains unclear whether and how the Dirac electrons fall into Cooper pairing in an intrinsic superconductor with the topological surface states. Here we show the systematic study of scanning tunnelling microscope/spectroscopy on the possible topological superconductor Sr<jats:sub><jats:italic>x</jats:italic></jats:sub>Bi<jats:sub>2</jats:sub>Se<jats:sub>3</jats:sub>. We first demonstrate that only the intercalated Sr atoms can induce superconductivity. Then we show the full superconducting gaps without any in-gap density of states as expected theoretically for a bulk topological superconductor. Finally, we find that the surface Dirac electrons will simultaneously condense into the superconducting state within the superconducting gap. This vividly demonstrates how the surface Dirac electrons are driven into Cooper pairs.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383951796098246790","@type":"Researcher","foaf:name":[{"@value":"Guan Du"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246793","@type":"Researcher","foaf:name":[{"@value":"Jifeng Shao"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246912","@type":"Researcher","foaf:name":[{"@value":"Xiong Yang"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246785","@type":"Researcher","foaf:name":[{"@value":"Zengyi Du"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246789","@type":"Researcher","foaf:name":[{"@value":"Delong Fang"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246788","@type":"Researcher","foaf:name":[{"@value":"Jinghui Wang"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246784","@type":"Researcher","foaf:name":[{"@value":"Kejing Ran"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246786","@type":"Researcher","foaf:name":[{"@value":"Jinsheng Wen"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246791","@type":"Researcher","foaf:name":[{"@value":"Changjin Zhang"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246792","@type":"Researcher","foaf:name":[{"@value":"Huan Yang"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246787","@type":"Researcher","foaf:name":[{"@value":"Yuheng Zhang"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951796098246794","@type":"Researcher","foaf:name":[{"@value":"Hai-Hu Wen"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"20411723"}],"prism:publicationName":[{"@value":"Nature Communications"}],"dc:publisher":[{"@value":"Springer Science and Business Media LLC"}],"prism:publicationDate":"2017-02-15","prism:volume":"8","prism:number":"1","prism:startingPage":"14466"},"reviewed":"false","dc:rights":["https://creativecommons.org/licenses/by/4.0","https://creativecommons.org/licenses/by/4.0"],"url":[{"@id":"https://www.nature.com/articles/ncomms14466.pdf"},{"@id":"https://www.nature.com/articles/ncomms14466"}],"createdAt":"2017-02-15","modifiedAt":"2022-12-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360009142873345792","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Electronic structures of \n<mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\"><mml:mrow><mml:msub><mml:mi>Bi</mml:mi><mml:mn>2</mml:mn></mml:msub><mml:msub><mml:mi>Se</mml:mi><mml:mn>3</mml:mn></mml:msub></mml:mrow></mml:math>\n and \n<mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\"><mml:mrow><mml:msub><mml:mi>Ag</mml:mi><mml:mi>x</mml:mi></mml:msub><mml:msub><mml:mi>Bi</mml:mi><mml:mn>2</mml:mn></mml:msub><mml:msub><mml:mi>Se</mml:mi><mml:mn>3</mml:mn></mml:msub></mml:mrow></mml:math>\n under pressure studied by high-resolution x-ray absorption spectroscopy and density functional theory calculations"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567189433890048","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Nematic Superconductivity in Doped Bi2Se3 Topological Superconductors"}]},{"@id":"https://cir.nii.ac.jp/crid/1360576118729009280","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Dirac lines and loop at the Fermi level in the time-reversal symmetry breaking superconductor LaNiGa2"}]},{"@id":"https://cir.nii.ac.jp/crid/1360846641753048960","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Full-gap superconductivity in spin-polarised surface states of topological semimetal β-PdBi2"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1038/ncomms14466"},{"@type":"CROSSREF","@value":"10.1103/physrevb.102.155118_references_DOI_1oHhO40Ij9PGYh8zK99opz7z5yy"},{"@type":"CROSSREF","@value":"10.1038/s41467-017-01209-9_references_DOI_1oHhO40Ij9PGYh8zK99opz7z5yy"},{"@type":"CROSSREF","@value":"10.3390/condmat4010002_references_DOI_1oHhO40Ij9PGYh8zK99opz7z5yy"},{"@type":"CROSSREF","@value":"10.1038/s42005-021-00771-5_references_DOI_1oHhO40Ij9PGYh8zK99opz7z5yy"}]}
