Enhanced dielectric properties with a significantly reduced loss tangent in (Mg, Al) co-doped CaCuTiO ceramics: DFT and experimental investigations.

CaCuTiO and CaCuMgTiAlO ceramics were fabricated a solid-state reaction method. A single-phase of CaCuTiO was found in these two ceramics. Very great grain size expansion was produced by co-doping with Mg and Al.

Colossal dielectric permittivity, reduced loss tangent and the microstructure of Ca Cd CuTiO F ceramics.

Ca Cd CuTiO F ( = = 0, 0.10, and 0.15) ceramics were successfully prepared a conventional solid-state reaction (SSR) method.

Gold-Nanoparticle-Deposited TiO Nanorod/Poly(Vinylidene Fluoride) Composites with Enhanced Dielectric Performance.

Flexible dielectric polymer composites have been of great interest as embedded capacitor materials in the electronic industry. However, a polymer composite has a low relative dielectric permittivity (ε' < 100), while its dielectric loss tangent is generally large (tanδ > 0.1).

Significantly Enhanced Dielectric Properties of Ag-Deposited (InNb)TiO/PVDF Polymer Composites.

The enhanced dielectric permittivity (ε') while retaining a low loss tangent (tanδ) in silver nanoparticle-(InNb)TiO/poly(vinylidene fluoride) (Ag-INTO/PVDF) composites with different volume fractions of a filler () was investigated. The hybrid particles were fabricated by coating Ag nanoparticles onto the surface of INTO particles, as confirmed by X-ray diffraction. The ε' of the Ag-INTO/PVDF composites could be significantly enhanced to ~86 at 1 kHz with a low tanδ of ~0.

Effects of Charge Compensation on Colossal Permittivity and Electrical Properties of Grain Boundary of CaCuTiO Ceramics Substituted by Al and Ta/Nb.

The effects of charge compensation on dielectric and electrical properties of CaCuTi(AlTaNb)O ceramics ( = 0-0.05) prepared by a solid-state reaction method were studied based on the configuration of defect dipoles. A single phase of CaCuTiO was observed in all ceramics with a slight change in lattice parameters.
