Quantification of flexoelectricity in PbTiO(3)/SrTiO(3) superlattice polar vortices using machine learning and phase-field modeling
Flexoelectricity refers to electric polarization generated by heterogeneous mechanical strains, namely strain gradients, in materials of arbitrary crystal symmetries. Despite more than 50 years of work on this effect, an accurate identification of its coupling strength remains an experimental challe...
