Abstract
We demonstrate 0–3 type heterogeneous NBT–NN–ST/HfO 2 composites to achieve high E b and P max . Some HfO 2 are concentrated in grain boundaries to suppress local electric branches’ development for enhancing E b while others diffuse into lattice to improve bonds’ polarity for maintaining high P max .
