Electrical Properties of Ionic Materials

This lecture discusses the electrical properties of ionic materials, which are composed of ions with positive and negative charges arranged in a network structure. These materials, unlike metals, do not have free electrons for current transport, making them highly resistive. However, they can still conduct electricity through mechanisms involving ion movement and defects in the material. The lecture explores how ions can change position, the impact of vacancies and interstitials on ion mobility, and the relationship between temperature, ion mobility, and conductivity in ionic materials.
