Abstract
Impedance spectroscopy is an appropriate technique for studying the complexity of materials, in which their different frequency relationships can be exploited in such a manner, they can be efficiently separated. Barium strontium titanate BaSrTiO3 (BST) is a ferroelectric material with unique properties that make it useful in a range of electronic applications. BST plays an important role in the field of gas-sensing applications. The potential application of BST material as a gas sensor for detecting nitrogen dioxide (NO2) in the atmosphere was studied. Impedance spectroscopy studies were conducted across a wide frequency range from 10-1 to 106 Hz, in the temperature range of 100°C to 350°C and a relative humidity of 50%, and in both air and the presence of NO2 in concentrations from 0.5 to 5 ppm. The results of the impedance analysis indicate that the broadband models, which comprise both single and parallel RC elements, can accurately represent the NO2 gas interaction mechanism with the gas-sensitive layer of the BST material. These models were found to effectively capture changes in parameters associated with the interaction.
