Polarization hysteresis and bipolar strain curves for a KNN and b PZT ceramics. c SEM image, d out-of-plane amplitude, and e phase image for KNN samples. The high-angle annular dark-field (HAADF) image for KNN viewed along [100]pc zone axis. f, g Polar vector mapping and h distribution mapping of polar vector angles that are off the [110] direction for KNN samples. i SEM image, j out-of-plane amplitude, and k phase image for PZT samples.
