Erratum: Enhanced size-dependent piezoelectricity and elasticity in nanostructures due to the flexoelectric effect [Phys. Rev. B 77, 125424 (2008)]

摘要

An error was found in the constitutive equations Eqs. (19) and (20) in our paper. Here we correct them. The central conclusions of our work (e.g., enhanced size-dependent piezoelectricity in nanostructures due to flexoelectricity) remain the same. In fact, corrected theoretical results in the case of BaTiO_3 in piezoelectric phase compare better with atomistics than in our original publication. We provide here the corrected equations and for completeness, the revised figures as well.
