Atomic-Site-Dependent Pairing Gap in Monolayer FeSe/SrTiO3(001)–(√13 × √13)

The interfacial FeSe/TiO2−δ coupling induces high-temperature superconductivity in monolayer FeSe films. Using cryogenic atomically resolved scanning tunneling microscopy/spectroscopy, we obtained atomic-site dependent surface density of states, work function, and the pairing gap in the monolayer Fe...
