Misfit dislocation, external

To demonstrate spontaneous flexoeffect contribution to the nanoferroic properties, we hereafter neglect the surface excess elastic moduli, surface stress tensor and surface piezoelectric effect contributions into the surface energy (4.11). We consider mechanically free nanoparticles without misfit dislocations, which should lead to the external flexoeffect only. The contribution of misfit dislocations into the flexoelectric effect in thin films has been considered in details by Catalan et al. [72, 73].
