Comment/Description

Content:
- Experimental techniques: quantities, broadband dielectric spectroscopy, nonlinear and polarization measurements
- Dynamic processes in dielectric materials: relaxation processes, phenomenological models
- Dielectric properties of disordered matter: liquids, glasses, plastic crystals
- Charge transport: hopping conductivity, universal dielectric response
- Ionic conductivity: conductivity mechanism, dielectric properties, advanced electrolytes for energy-storage devices
- Maxwell-Wagner relaxations: equivalent-circuits, applications (supercapacitors), colossal-dielectric-constant materials
- Electroceramics: Materials, Properties (relaxor ferroelectric, ferroelectric, antiferroelectric and multiferroic), Applications

Examinations:
As noted in the handbook of modules, the examination for this lecture will be an oral talk of 45 min. The talks will either extend topics, already treated in the lecture, or they will be about additional topics in the field of dielectric materials. The talks will be given towards the end of the semester and we will provide a list of available topics.
