Abstract
We study the influence of temperature on the interaction of nano-pores with ferroelectric domain walls in bulk single-crystalline lead zirco-
nate titanate as a function of pore size and concentration. Using a density functional theory-informed finite-temperature phase-field model,
we determine the electric field required to unpin 180 -domain walls from a periodic array of pores, thus gaining insight into the effect of tem-
perature on domain wall kinetics in ferroelectrics with good qualitative agreement between simulated results and experimental
measurements.
