In this research paper, our central focus is upon investigating structural and electrical properties of polycrystalline Ba0.9Ag0.1TiO3 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 Ba0.9Ag0.1TiO3 follows the correlated barrier hopping (CBH) model.

Ba0.9Ag0.1TiO3化合物的电导率和介电分析
在本研究论文中,我们的重点是研究通过标准固态反应技术制造的多晶 Ba0.9Ag0.1TiO3 粉末的结构和电学特性。室温下的 X 射线衍射分析证实该组分以四方和斜方结构结晶。在 540 K–620 K 的温度范围和 67. 5 Hz 到 1 MHz 的频率范围内,通过复阻抗谱研究了电响应。研究结果表明,阻抗的虚部 (Z'') 作为实部 (Z') 的函数在不同温度下的变化呈现半圆弧。设置了一个类似的电路来解释阻抗数据。
