Abstract Porous carbon are excellent electrode materials for energy-storage devices. Here, we present a facile in-situ reduction method to improve the electrochemical performance of by gold nanoparticles. The prepared porous microspheres decorated with gold-nanoparticle had 3D honeycomb-like structure high specific surface area about 1635 m 2 g −1 , confirmed scanning electron microscopy, transmission and Brunauer-Emmett-Teller method. as-synthesized was exemplified as supercapacitor...
Due to its lead-free composition and a unique double polarization hysteresis loop with large maximum (<i>P</i><sub>max</sub>) small remnant (<i>P</i><sub>r</sub>), AgNbO<sub>3</sub>-based antiferroelectrics (AFEs) have attracted extensive research interest for electric energy storage applications. However, low dielectric breakdown field (<i>E</i><sub>b</sub>) limits an density further development. In this work, highly efficient method was proposed fabricate high-energy-density...
BiFeO₃/BaTiO₃ bi-layer thick films (~1 μm) were deposited on Pt/Ti/SiO₂/(100) Si substrates with LaNiO₃ buffer layers at 500 °C via a rf magnetron sputtering process. X-ray diffraction (XRD) analysis revealed that both BiFeO₃ and BaTiO₃ have (00l) preferred orientation. The showed small remnant polarization (Pr ~ 7.8 μC/cm²) large saturated (Ps 65 μC/cm²), resulting in slim polarization-electric field (P-E) hysteresis loop improved energy storage characteristics (Wc = 71 J/cm³, η 61%)....
As a prototype single-phase multiferroic, BiFeO3 exhibits excellent electrical, magnetic, and magnetoelectric properties, appealing to many modern technological applications. One of its overlooked merits is high piezoelectric performance originating from large remnant polarization (Pr) low dielectric constant (εr). Furthermore, Curie temperature coercive field ensure good stabilities in device However, achieve close-to-intrinsic processing usually used for the preparation highly crystalline...
High energy density dielectric film capacitors are desirable in modern electronic devices. Their miniaturization and integration into Si-based microsystems create opportunities for in-circuit supply, buffering, conditioning. Here, we present a CMOS (complementary metal oxide semiconductor)-compatible route the fabrication of BaTiO3 on Si with record-high recoverable good efficiency (∼242 J/cm3 ∼76% at 8.75 MV/cm). These films were sputter-deposited 350 °C consisted slightly compressed...
Achieving an excellent energy storage performance, together with a high cycling reliability, is desirable for expanding the technological applications of ferroelectric dielectrics. However, in well-crystallized material, concomitant polarizability and low polarization-saturation field have led to square-shaped polarization-electric loop, fatally impairing both recoverable density (<em>W</em><sub>rec</sub>) efficiency (<em>η</em>). Nanocrystalline films macroscopically amorphous structure...
The excellent energy storage performances of dielectric materials, a high density and efficiency, the stability in wide range temperature, frequency cycling time, are surely desirable for devices. A trade-off relationship between polarization breakdown strength, however, limits enhancement properties materials. To effectively boost efficiency capacitors, by inserting BiFeO3 layer into BaTiO3 film present case, symmetric BaTiO3/BiFeO3/BaTiO3 tri-layer heterostructure with...
