Polarization properties of ZnO and BeO: An ab initio study through the Berry phase and Wannier functions approaches

Noel, Y., Zicovich-Wilson, C. M., Civalleri, B., D’Arco, Ph., Dovesi, R.·2001·Physical Review B

Abstract

The spontaneous polarization and the piezoelectric constants of ZnO and BeO are calculated at an ab initio quantum-mechanical level by using two alternative strategies, namely, through the Berry phase scheme applied to delocalized crystalline orbitals, and through the definition of well-localized Wannier functions. The two sets of results, obtained in the same computational conditions (both schemes are implemented in the CRYSTAL code) compare extremely well, and are in good agreement with available experimental data.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
