Non-conventional mechanism of ferroelectric fatigue via cation migration
Ferroelectric fatigue degrades ferroelectric properties upon polarization cycling, but its underlying chemistry is poorly understood. Here, the authors show by multimodal chemical imaging that fatigue in PbZr0.2Ti0.8O3 thin films is associated with Cu + ions migration from the electrode into the fil...
