In the research field of energy storage dielectrics,the“responsivity”parameter,defined as the recyclable/recoverable energy density per unit electric field,has become critically important for a comprehensive evaluation of the energy storage capability of a *** this work,high recyclable energy density and responsivity,i.e.,W_(rec)=161.1 J·cm^(-3) and ξ=373.8 J·(kV·m^(2))^(-1),have been simultaneously achieved in a prototype perovskite dielectric,BaTiO_(3),which is integrated on Si at 500℃ in the form of a submicron thick *** ferroelectric film features a multi-scale polar structure consisting of ferroelectric grains with different orientations and inner-grain ferroelastic domains.A LaNiO_(3) buffer layer is used to induce a{001}textured,columnar nanograin microstructure,while an elevated deposition temperature promotes lateral growth of the nanograins(in-plane diameter increases from~10-20 nm at lower temperatures to~30 nm).These preferably oriented and periodically regulated nanograins have resulted in a small remnant polarization and a delayed polarization saturation in the film’s P-E behavior,leading to a high recyclable energy ***,an improved polarizability/dielectric constant of the BaTiO_(3) film has produced a much larger maximum polarization than those deposited at lower temperatures at the same electric field,leading to a record-breaking responsivity for this simple perovskite.

Achieving an excellent energy storage performance,together with high cycling reliability,is desirable for expanding technological applications of ferroelectric ***,in well-crystallized ferroelectric materials,the concomitant high polarizability and low polarization saturation field have led to a square-shaped polarization–electric field loop,fatally impairing both recoverable energy density(W_(rec))and efficiency(η).Nanocrystalline ferroelectric films with a macroscopically amorphous structure have shown an improved W_(rec) andη,but their much lower polarizability demands an extremely high electric field to achieve such performances,which is undesirable from an economic ***,we propose a strategy to boost the energy storage performances and stability of ferroelectric capacitors simultaneously by constructing a tri-layer film in which a well-crystallized ferroelectric layer was sandwiched by two pseudo-linear dielectric layers with a dominant amorphous *** sol–gel-derived BaTiO_(3)/(Pb,La,Ca)TiO_(3)/BaTiO_(3)(BTO/PLCT/BTO)tri-layer films,we show that the above design is realized via rapid thermal annealing which fully crystallized the middle PLCT layer while left the top/bottom BTO cap layers in a poor crystallization *** sandwiched structure is endowed with an enhanced maximum polarization while a small remnant one and a much-delayed polarization saturation,which corresponds to large W_(rec)≈80 J/cm^(3) and highη≈86%.Furthermore,the film showed an outstanding cycling stability:its W_(rec) andηremain essentially unchanged after 10^(9) electric cycles(DW/W<4%,Dη/η<2%).These good energy storage characteristics have proved the effectiveness of our proposed strategy,paving a way for the utilization of sandwiched films in applications of electric power systems and advanced pulsed-discharge devices.
