Abstract
Key observation is the reversible phase transition of strained BFO thin films with excellent pyroelectric response. Using in situ HRTEM, the atomic-scale movement of the phase boundary and the origin of the phase transition are revealed. The phase transition involves the migration of the phase boundary, which is a prerequisite for the growth of the T-like phase and requires an intermediate phase (highly distorted R-phase) as a precursor, which was verified using FFT diffraction patterns. This result adds to the understanding of multifunctional complex oxide materials.436
