Abstract
Ab initio density functional theory has been used to study the electronic band structure, k=0k=0 (zone center) vibrational modes, and dielectric properties of the crystalline high-κκ perovskite oxide SrZrO3. The frequencies of the k=0k=0 normal modes are computed by the linear response technique and then grouped according to their symmetry. The dielectric intensity of each IR-active mode has been determined. It is found that the calculated orientationally averaged static dielectric constant ε0=21.49ε0=21.49 is in good agreement with experiment.
