The effect of applied mechanical strains on the ferroelectric and dielectric properties of a model single crystal is investigated using a phase field model based on the time-dependent Ginzburg–Landau equation, which takes both multiple-dipole–dipole-electric and -elastic interactions into account. The evolution of the ferroelectric domain structure is simulated at different temperatures and applied...
Polarization switching in a ferroelectric subjected to an electric field or a stress field is simulated using a phase-field model based on the time-dependent Ginzburg-Landau equation, which takes both multiple-dipole-dipole-electric and multiple-dipole-dipole-elastic interactions into account. The temporal evolution of the polarization switching shows that the switching is a process of nucleation,...
