| Abstract: |
The discovery of interfacial superconductivity in monolayer FeSe/oxides has spurred intensive research interest. Here we not only extend the FeSe/FeOxsuperconducting interface to FeSe/NdFeO3but also establish robust interface-enhanced superconductivity at a very low doping level. Specifically, well-annealed FeSe/NdFeO3exhibits a low doping level of 0.038–0.046 e–/Fe with a larger superconducting pairing gap without a nematic gap, indicating an enhancement of the enhanced superconducting pairing strength and suppression of nematicity by the FeSe/FeOxinterface compared with those of thick FeSe films. These results improve our understanding of the roles of the oxide interface in the low-electron-doped regime. |
