“…On the other hand, the bulk-limited mechanism relies on the electrical properties intrinsic to the dielectric itself. Analysis of this mechanism yields essential physical parameters within the dielectric, including trap level, trap spacing, trap density, carrier drift mobility, dielectric relaxation time, and density of states in the conduction band [45].…”

This study presents a comprehensive investigation into the structural, morphological, and electrical properties of sol-gel synthesized Ba0.75Ni0.25Tc0.88Mn0.12O3 perovskite ceramic (BNTMO). The meticulous preparation protocol, involving solvating various precursors, was followed by an extensive characterization employing X-ray diffraction, scanning electron microscopy, and dielectric studies. XRD analysis affirmed the single-phase single-phase cubic structure with Pm-3m space, while SEM revealed a well-defined morphology with an average particle size of 243 nm. The electrical conductivity exploration, elucidated through Jonscher’s universal power law, provided insights into charge carrier dynamics, exhibiting semiconductor behavior. Impedance spectroscopy unraveled a distinctive relaxation peak, corroborated by Cole-Cole plots, unveiling a unique charge carrier mechanism. Dielectric studies showcased intriguing polarization dynamics, indicating promising applications in energy storage. The convergence of activation energy values from various analyses underscores the coherence in the charge carrier relaxation process. Overall, our findings contribute to a nuanced understanding of the electrical intricacies of BNTMO, presenting avenues for its utilization in advanced technological applications. Graphical Abstract
