Abstract

This study presents a comprehensive investigation of the crystal structure and DC conduction mechanism of [(Ba0.7-x Lax) Bi0.3][(Ti0.5 Zr0.2) Fe0.3]O3 with x = 0.00, 0.01, 0.03, 0.05 employing X-ray diffraction (XRD) and electrical conductivity measurements. Various compositions were synthesized through the solid-state ceramic route. XRD was used to investigate phase formation. Analysis of XRD data suggested a structural transition from cubic to tetragonal for x ≥ 0.01. The average crystallite size first increases for x = 0.01 and then decreases for x ≥ 0.03. The temperature-dependent electrical conductivity measurements were investigated over a wide temperature range which revealed distinct conductivity mechanisms governing the material's transport properties. The activation energy (Ea) has been estimated from temperature-dependent DC conductivity. Overall, this study provides valuable insights into the correlation between crystal structure and electrical properties in [(Ba0.7-x Lax) Bi0.3][(Ti0.5 Zr0.2) Fe0.3]O3, offering significant implications for its potential applications in electronic and optoelectronic devices requiring tailored conductivity characteristics.
