Electron—phonon Coupling and the Superconducting Phase Diagram of the LaAlO3—SrTiO3 Interface
Electron—phonon Coupling and the Superconducting Phase Diagram of the LaAlO3—SrTiO3 Interface
The superconductor at the LaAlO3-SrTiO3 interface provides a model system for the study of two-dimensional superconductivity in the dilute carrier density limit. Here we experimentally address the pairing mechanism in this superconductor. We extract the electron-phonon spectral function from tunneling spectra and conclude, without ruling out contributions of further pairing …
