Oxygen Vacancy Induced Flat Phonon Mode at FeSe /SrTiO(3) interface
A high-frequency optical phonon mode of SrTiO(3) (STO) was found to assist the high-temperature superconductivity observed recently at the interface between monolayer FeSe and STO substrate. However, the origin of this mode is not clear. Through first-principles calculations, we find that there is a...
