Atomistic determination of flexoelectric properties of crystalline dielectrics
Atomistic determination of flexoelectric properties of crystalline dielectrics
Upon application of a uniform strain, internal sub-lattice shifts within the unit cell of a non-centrosymmetric dielectric crystal result in the appearance of a net dipole moment: a phenomenon well known as piezoelectricity. A macroscopic strain gradient on the other hand can induce polarization in dielectrics of any crystal structure, …
