Polar discontinuity screening by charge disproportionation in ferroelectric-nickelate superlattices
Edith Simmen, Jonathan Amara, Philippe Ghosez +1
We use density functional theory (DFT) to demonstrate rearrangement of charge disproportionation as a new mechanism for screening polar discontinuities at heterointerfaces. We focu…
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…
Journal Research Data Policies in Materials Science
Lukas Hörmann, Hemanadhan Myneni, Rwayda Kh. S. Al-Hamd +17
Open and reproducible research in materials science relies on the availability of data, code, and common metadata standards. Journal research data policies (RDPs) remain a primary…
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…
