Figure 10. Enhanced ESP in BT-based glass ceramics via defect formation modulation leading to an “amorphous-disordered-ordered” microstructure. (A) Schematic illustrating defect formation during crystallization without and with electric field assistance; (B) High-resolution TEM image of BTAS glass ceramic showing morphology and lattice fringes; insets display the selected area electron diffraction pattern and grain size distribution histogram; (C) P-E loops of BTAS glass ceramics measured at 10 Hz. The BTAS composition corresponds to glass ceramics crystallized under a 3 kV/cm electric field. This figure is quoted with permission from Shang et al.^[101]. ESP: Energy storage performance; TEM: transmission electron microscopy; BT: BaTiO₃; BTAS: BaO-TiO₂-Al₂O₃-SiO₂.
