2. The contribution of impedance spectroscopy to the study of these devices

2.1 Principle of impedance spectroscopy

A technique of choice for measuring the electrical conductivity of a ceramic material is complex impedance spectroscopy [P 2 210] . This technique is based on characterizing the response of a sample to a sinusoidal alternating voltage of variable frequency. The electrical properties of a material are due to its conduction and dielectric properties. For the simplest cases, oxide ion conductors can be described as the parallel association of an intrinsic resistance...
