Figure 7. Enhancing temperature stability through domain engineering. (A) Temperature-dependent S_neg for the composition with x = 0.006. (B) Temperature-dependent d₃₃* for four compositions with different phase boundaries. (C) Normalized temperature-dependent d₃₃* against the room-temperature values. Temperature-dependent (D) P-E loops and (E) Bipolar S-E curves of the x = 0.006 composition. (F) Phase angle loops and (G) piezo-response curves of the selected region. (H and I) Domain structures of KN_0.6NS_0.045-0.006BF-0.03BNZ ceramics. Schematic diagram illustrating domain switching at (J) room temperature and (K) high temperature.
