Polarizing ultrathin ferroelectric BaTiO3 films through interfacial layer polarization
Ipek Efe, Edith Simmen, Tobias Goldenberger +3
An important requirement for the integration of ferroelectric thin films into devices is deterministic control of the polarization state in films of only a few unit cells in thickn…

Interplay of metallicity, ferroelectricity and layer charges in SmNiO/BaTiO superlattices
Edith Simmen, Nicola A. Spaldin
Using density-functional theory, we demonstrate that the formal layer charges of the metallic samarium nickelate electrode influence the spontaneous ferroelectric polarization of t…
