Fig. 5: Phase-field simulation results of polarization, strain, and P–E behavior in BNBT thin films with and without planar defects.

Phase-field simulations display polarization mapping in a the initial BNBT and b the bound charge-modified BNBT. Strain mapping results of c initial BNBT and d bound charge-modified BNBT. The simulated P-E loops for e initial BNBT and f bound charge-modified BNBT. Enlarged views of the polarization mapping for g initial BNBT and h bound charge-modified BNBT, which are derived from a, b, respectively.
