Super-tetragonal ferroelectric barium titanate through anionic overstoichiometry
Ferroelectric oxides, characterized by an electrical polarization that is switchable with an electric field, are an appealing class of materials for energy-efficient computing, electronics, and photonics. In thin films, the properties of ferroelectrics are commonly tuned using substrate-imposed epitaxial strain, an app...
