Electrical conductivity and dielectric analysis of Ba0.9Ag0.1TiO3 compound

In this research paper, our central focus is upon investigating structural and electrical properties of polycrystalline Ba 0.9 Ag 0.1 TiO 3 powder which was fabricated through standard solid-state reaction technique. X-ray diffraction analysis at room temperature confirmed that the component crystallizes in both tetragonal and orthorhombic structures. The electrical response was explored by complex impedance spectroscopy in the temperature range of 540 K–620 K and frequency from 67. 5 Hz to 1 MHz. The findings demonstrated that the variation of the imaginary part of impedance (Z'') as a function of the real one (Z') at various temperatures presented semicircle arcs. An electrical similar circuit was set forward to interpret the impedance data. The results obtained from the temperature dependence of the exponent s suggest that the transport process of the charge carriers in the compound Ba 0.9 Ag 0.1 TiO 3 follows the correlated barrier hopping (CBH) model.
