Electrical properties of improper ferroelectrics from first principles
Massimiliano Stengel, Craig J. Fennie, Philippe Ghosez
We study the interplay of structural and polar distortions in hexagonal YMnO3 and short-period PbTiO3/SrTiO3 superlattices by means of first-principles calculations at constrained…
