Origin of charge transfer and enhanced electron–phonon coupling in single unit-cell FeSe films on SrTiO3

The origin of interface charge transfer and electron-phonon coupling in single unit-cell FeSe on SrTiO3 remains elusive. Here, Zhang et al. report strengthened Ti-O bond and band bending at the FeSe/SrTiO3 interface, which leads to several important processes.
