Discretisation originated Peierls–Nabarro barriers in simulations of ferroelectrics
Original language description
We have analysed domain-wall-motion-related energy barriers, which originate from the regular discretisation grid utilised in phase-field simulations of ferroelectric materials. We develop three approaches to determine the barrier height, and we demonstrate these on a specific model of BaTiO3. All lead to comparable results. Finally, we show that the barrier properties for both 180∘ and 90∘ domain walls depend on the size of the discretisation step and the distance between the domain walls.
