Studies of structural, microstructural, dielectric, and electrical characterization of BiNaZnMoO\(_{6}\) double perovskite

This study investigates the structural, microstructural, dielectric, and electrical properties of BiNaZnMoO₆ (BNZM) ceramic synthesized using a conventional solid-state reaction method. Preliminary structural analysis using X-ray diffraction (XRD) suggests orthorhombic crystal symmetry. Scanning electron microscopy (SEM) micrographs reveal a uniform distribution of well-grown grains with well-defined grain boundaries, which may contribute to the enhanced dielectric properties. Energy dispersive X-ray spectroscopy (EDX) analysis confirms the presence of all constituent elements Bi, Na, Zn, Mo, and O in the studied sample. Dielectric spectra analysis as a function of frequency and temperature indicates the formation of high-quality dielectric materials, evidenced by a high dielectric constant and low loss. Impedance spectroscopy supports the semiconducting nature of the sample. Modulus analysis reveals a non-Debye type of relaxation process. The study of AC conductivity suggests a thermally activated conduction mechanism. Furthermore, Cole-Cole and Nyquist plots confirm the semiconducting behavior, which is corroborated by resistance versus temperature analysis. These findings suggest potential applications in energy storage devices.
