We begin by calculating the TO phonon frequencies of the alkaline earth oxides as a function of epitaxial strain to search for the onset of a softening or instability.
Strain-induced ferroelectricity in simple rocksalt binary oxides
Now that we have demonstrated the possibility of inducing ferroelectricity in BaO thin lms under epitaxial strain, we investigate if the phenomenon is specic to BaO or a more general feature shared with other alkaline earth compounds.
