Figure 3. Diffuse phase transition and composition-induced structural flexibility to enhance the temperature stability. (A) Dielectric-temperature curves of different compositions. (B) The PPT point of LxKNNSy-BZ-BNH-1Mn compositions. (C) The d₃₃ of the LxKNNSy-BZ-BNH-1Mn composition at room temperature. (D) Variation of d₃₃ with temperature. (E) In situ temperature neutron diffraction of the (002)_PC reflection peak of the x = y = 0 and x = y = 0.025 samples. (F) PFM images of the x = y = 0.025 sample in both virgin state and local poling states at different temperatures. This figure quoted with permission^[29]. Copyright 2020, Oxford University Press.
