Ab initio Study of Cross-Interface Electron-Phonon Couplings in FeSe Thin Films on SrTiO${}_3$ and BaTiO${}_3$

Yan Wang, Andreas Linscheid, Tom Berlijn +1

We study the electron-phonon coupling strength near the interface of monolayer and bilayer FeSe thin films on SrTiO${}_3$, BaTiO${}_3$, and oxygen-vacant SrTiO${}_3$ substrates, using ab…
