Abstract
Impedance Spectroscopy technique was employed in order to characterize nanostructured powders based on solid solutions of SnO 2 and TiO 2, employed in thick-film chemoresistive gas sensors. The measurements were performed with a cylindrical capacitor, manufactured for this specific purpose, with the powders used as dielectric between the plates. Results were interpreted with the support of a theoretical model, which describes the electrical properties of the powders and allows us to estimate their relative permittivity. © 2012 Springer Science+Business Media, LLC.File in questo prodotto:
