Flexoelectric fracture-filter effect in ferroelectrics
Kumara Cordero-Edwards, Hoda Kianirad, Jordi Sort +2
The propagation front of a crack generates large strain gradients and it is therefore a strong source of gradient-induced polarization (flexoelectricity). Herein, we demonstrate th…

Intrinsic ionic screening of the ferroelectric polarization of KTP
Mario Maglione, Anand Theerthan, Vincent Rodriguez +4
Mobile charges and lattice polarization interact in ferroelectric materials because of the Coulomb interaction between the mobile free charges and the fixed lattice dipoles. We hav…
