Fig. 3: Structure analysis of the high-entropy sample.

Bright-field TEM images and SAED patterns of the BNSLTMZ ceramics taken from (a) the [001]C zone axis and (b) the [110]C zone axis. HAADF-STEM images of (c) the BNSLTMZ ceramics, recorded along the [100]C zone axis, and magnified images of selected areas from (c) representing R, T, and C nanodomains respectively. The yellow arrows show the displacement of A-site cation in each unit cell, and the green and orange spheres representing A- and B-site cations, respectively. d The cation displacement vector mapping. Statistical distribution of (e) polarization angle and (f) polarization magnitude. g Statistical distribution of the amplitude and angle of the polarization vector.
