The Effect of Symmetry Lowering on the Dielectric Response of $BaZr{O}_3$

Joseph W. Bennett, Ilya Grinberg, Andrew M. Rappe

We use first-principles density functional theory calculations to investigate the dielectric response of BaZrO${}_3$ perovskite. A previous study [Arkbarzadeh {\em et al.} Phys. Rev.…
