On the nonlinear dielectric response of ferroelectric polydomain films controlled by crystal lattice defects
Original language description
It is known that the dielectric response of polydomain ferroelectrics is to a large extent controlled by the dynamics of domain wall motions. The details of the interaction of the domain walls with crystal lattice defects are presented. The general phenomenological models for the reversible and irreversible movements of the domain walls in the ferroelectric with crystal lattice defects is presented. These phenomenological models will be compared with numerical Phase Field Modeling simulations of the interaction of crystal lattice defects with ferroelectric domain walls. The cases of the both 180 and 90 domain walls are presented.The ageing of dielectric response of BaTiO3 films and we will compare the results of our simulations with experimental data is discussed.
