Electrically driven octahedral rotations in SrTiO3 and PbTiO3
Jiawang Hong, David Vanderbilt
We investigate the oxygen octahedral rotations that occur in two perovskites, SrTiO3 and PbTiO3, as a function of applied three-dimensional electric displacement field, allowing us…

External uniform electric field removing flexoelectric effect in epitaxial ferroelectric thin films
Hao Zhou, Jiawang Hong, Yihui Zhang +3
Using the modified Landau-Ginsburg-Devonshire thermodynamic theory, it is found that the coupling between stress gradient and polarization, or flexoelectricity, has significant eff…

Flexoelectricity induced increase of critical thickness in epitaxial ferroelectric thin films
Hao Zhou, Jiawang Hong, Yihui Zhang +3
Flexoelectricity describes the coupling between polarization and strain/stress gradients in insulating crystals. In this paper, using the Landau-Ginsburg-Devonshire phenomenologica…
