Inferior interfacial superconductivity in 1 UC FeSe/SrVO${}_3$/SrTiO${}_3$ with screened interfacial electron-phonon coupling

Nan Guo, Xiaoyang Chen, Tianlun Yu +10

Monolayer FeSe/TiO${}_x$ and FeSe/FeO${}_x$ interfaces exhibit significant superconductivity enhancement compared to bulk FeSe, with interfacial electron-phonon coupling (EPC) playing…
