Abstract

Fabrication and energy-storage performance of (Pb,La)(Zr,Ti)O3 antiferroelectric thick films derived from polyvinylpyrrolidone-modified chemical solution J. Appl. Phys. 112, 034105 (2012); 10.1063/1.4742128Energy-storage performance and electrocaloric effect in (100)-oriented Pb0.97La0.02(Zr0.95Ti0.05)O3 antiferroelectric thick films

Ab initio hybrid DFT calculations of BaTiO3, PbTiO3, SrZrO3 and PbZrO3 (111) surfaces

“…Double polarization vs electric field hysteresis loops were obtained due to fully [111] pseudo-cubic orientation. Sa et al [32] proposed a method to improve charge and energy storage performance of PbZrO 3 thin films by ␣-Fe 2 O 3 nanoparticles doping. The PbZrO 3 thin films were deposited on Pt(111)/Ti/SiO 2 /Si substrates.…”

Enhancement of energy storage density in antiferroelectric PbZrO3 films via the incorporation of gold nanoparticles

“…It has been reported that compared with pure PZO films, the recoverable energy storage density and efficiency at 600 kV/cm could be increased by 33% and 10% in the 1‐mol%‐Eu‐doped PZO film, respectively . The restorable energy storage density and efficiency at 600 kV/cm of the α‐Fe 2 O 3 ‒PZO composite films were 69.6% and 16% higher than those of the pure PZO film . In this study, compared with pure PZO films, the recoverable energy storage density and efficiency at 600 kV/cm for the Au–PZO films with 1 mol% Au is increased by 42% and 25%.…”

“…Recently, Cazacu et al 28 showed a proof that the local field could be generated by using Au NPs as fillers in nonlinear dielectric matrix. Sa et al 15 also reported that the P max could be increased by α-Fe 2 O 3 NPs in the antiferroelectric α-Fe 2 O 3 -PZO nanocomposite. Therefore, in this work, enhanced P max in the Au-PZO films with 1% mol Au may be due to the locally intensified electric field around the embedded Au NPs, which can increase the displacement of Pb 2+ .…”

“…For instance, α-Fe 2 O 3 nanoparticles (NPs) of stratified distribution in the PZO films could increase the recoverable energy storage density from 10.5 to 17.4 J/cm 3 (at 600 kV/cm) due to local electric fields around the α-Fe 2 O 3 NPs. 15 It has also been reported that the addition of noble metal NPs in ferroelectric films could improve the ferroelectric properties in recent years. 16,17 Paik et al investigated the effect of Ag NPs on the ferroelectric properties of Ag-P(VDF-TrFE) composite films, and reported that compared with the pure P(VDF-TrFE) films, the saturation polarization of Ag-P(VDF-TrFE) composite films greatly improved due to the increase in the effective electric field induced by the reduction in the effective volume.…”

“…In addition, adding a second phase in AFE films can also improve AFE properties and the energy storage capacity. For instance, α‐Fe 2 O 3 nanoparticles (NPs) of stratified distribution in the PZO films could increase the recoverable energy storage density from 10.5 to 17.4 J/cm 3 (at 600 kV/cm) due to local electric fields around the α‐Fe 2 O 3 NPs . It has also been reported that the addition of noble metal NPs in ferroelectric films could improve the ferroelectric properties in recent years .…”
