The energy storage density of the film grown at 0.135 mbar is the largest among these three films and can go up to ∼69.1 J·cm -3 with energy storage efficiency of ∼73.3 %, owing to the highest breakdown strength and slim P - E loops.
In the present work, the synergistic combination of mechanical bending and defect dipole engineering is demonstrated to significantly enhance the energy storage performance of freestanding ferroelectric thin films, achieved through the generation of a narrower and right-shifted polarization-electric field hysteresis loop.
Through the integration of mechanical bending design and defect dipole engineering, the recoverable energy storage density of freestanding PbZr 0.52 Ti 0.48 O 3 (PZT) ferroelectric films has been significantly enhanced to 349.6 J cm −3 compared to 99.7 J cm −3 in the strain (defect) -free state, achieving an increase of ≈251%.
Furthermore, as the degree of bending increases, the flexoelectric field also becomes more pronounced, leading to a more significant shift in the Pz - Ez hysteresis loops and ultimately resulting in an enhanced energy storage density.
Taking PZT, which exhibits the most significant improvement among the four ferroelectric materials, as an example, the recoverable energy storage density has a remarkable enhancement with the gradual increase in defect dipole density and the strengthening of in-plane bending strain.
