Investigation of AC electrical conductivity and dielectric properties of BiBaFeZnO6 double perovskite oxides

Robust and Flexible Piezoelectric Lead-Free Zn-BCZT/PVDF-HFP Nanogenerators for Wearable Energy Harvesting

“…As shown in Figure 8, the Nyquist plots of BCZT/PVDF-HFP and Zn-BCZT/ PVDF-HFP composites reveal an apparent single component, which validates the good dielectric and conductivity properties of the realized composites as a result of their good homogeneity. 52,54 A single flattened semicircular arc shows a non-Debye type of relaxation with the center located below the real Z′ axis. Stress−stress processes, grain orientation, and atomic defect distribution may all contribute to this deviation from the ideal Debye mature.…”

Exploring bismuth-doped polycrystalline ceramic Ba0.75Bi0.25Ni0.7Mn0.3O3: synthesis, structure, and electrical properties for advanced electronic applications

“…Moreover, these materials have been investigated for their potential as promising candidates for the next generation of electronics due to their dual eddy and magnetization properties. [12][13][14] Additionally, perovskite oxides at room temperature can exhibit a variety of crystalline structures, such as cubic (Pm3), tetragonal (I4/m), monoclinic (P2 1 / n), and rhombohedral (R3c) systems. [15][16][17] Among the double perovskite materials, the oxide BiBaFeZnO 6 , conforming to the general formula A ′ A ′′ B ′ B ′′ O 6 (A ′ = La, Bi, Sr, A ′′ = Ba, B ′ = Ni, B ′′ = Nb, Mn, Fe), has been synthesized using the sol-gel method, with dielectric, electrical, temperature, and frequency dependencies being investigated.…”

Investigation of the structural, dielectric, magnetic properties and NTC-thermistor response of CaBiFeMnO6 double perovskites

“…[62][63][64] Since localized charge carriers participate in this conduction process, polaron entities arise at places close by. [64][65][66] The AC conductivity versus frequency plot shows a plateau and a dispersion. The plateau region indicates the presence of long-range DC conductivity at lower frequencies, while the dispersion zone highlights localised AC conductivity at higher frequencies.…”
