The charge transport mechanism and the macroscopic dielectric constant in polycrystalline materials commonly consist of several contributions such as sampleelectrode interface, grain boundary and bulk resistance/capacitance. Impedance spectroscopy is shown to be a powerful tool to account for and model such behaviour. In order to gain precise understanding of the functionality of polycrystalline electroceramic materials it is essential to deconvolute these contributions.Read More
