a SEM images of polished and thermally etched 0.5NN-0.5BNT-cs. b Room-temperature bright-field TEM images of 0.5NN-0.5BNT-cs and SAED patterns recorded along the c [100]c, and d [110]c for the core and shell regions, where red arrows point to superlattice diffraction points and yellow arrows point to satellite diffraction points. e EDS mapping images and f EDS line scan across core and shell in 0.5NN-0.5BNT-cs by TEM. Simulation of g Electrical field distribution, and h Electric tree evolution for 0.5NN-0.5BNT, 0.5NN-0.5BNT-s, and 0.5NN-0.5BNT-cs.
