Abstract
Nanotopological domains such as skyrmions, bubbles, and mesons in ferroelectric thin films offer fascinating physical properties as well as potential applications. Particularly, topological bubble domains demonstrate extraordinary piezoelectric response enhancement, yet the fundamental mechanism remains ambiguous. Here, bubble domains were induced in Bi0.5Na0.5TiO3-based films by competition among charge, orbital, and lattice degrees of freedom, demonstrating domain-density-dependent piezoelectric enhancement. A combination of experimental and theoretical simulations elucidated that the strong coupling of lattice distortion and oxygen octahedral distortion leads to an augment in local inhomogeneity, resulting in the increased density of bubble domains. Bubble domains with low-angle domain walls and high electric field sensitivity promoted polarization rotation and thus improved the piezoelectric properties. This study establishes a structure-property relationship for topological domains while providing guidelines for designing high-performance nanoelectronic devices based on domain engineering strategies.

Abstract
Ceramic capacitors have great potential for application in power systems due to their fantastic energy storage performance (ESP) and wide operating temperature range. In this study, the (1 - x)Bi0.5Na0.47Li0.03Sn0.01Ti0.99O3-xKNbO3 (BNLST-xKN) energy storage ceramics were synthesized through the solid-phase reaction method. The addition of KN disrupts the long-range ferroelectric order of the BNLST ceramic, inducing the emergence of polar nanoregions (PNRs), which enhances the ESP of the ceramics. The BNLST-0.2KN ceramic demonstrates a high recovered energy density (Wrec ∼ 3.66 J/cm3) and efficiency (η ∼ 85.8%) under a low electric field of 210 kV/cm. Meantime, it exhibits a large current density (CD ∼ 831.74 A/cm2), high power density (PD ∼ 78.86 MW/cm3), and fast discharge rate (t0.9 ∼ 0.1 μs), along with good temperature stability and excellent fatigue stability. These properties make the BNLST-0.2KN ceramic a promising candidate for energy storage applications in low electric fields.
