Abstract
Motivated by the high superconducting transition temperature of monolayer FeSe on , we propose a potential three-dimensional high-temperature superconductor superlattice FeSe- and study its structural stability and electronic structure using density functional theory. We find that the binding energy between the FeSe and layers is about eV per () unit and that it saturates already within a single atomic layer of . In addition we analyzed the dynamical stability of the superlattice and compared it to the case of bulk .
