Abstract: Solids can have a wide variety of structural and functional properties. In terms of electrical conductivity, they are used as metallic conductors, semiconductors or insulators. Ceramic materials can even show superconductivity at practically usable temperatures. In addition, ceramics are also able to transport ions. In many cases this conductivity is low, but in some cases it is very high and of practical importance due to structural disorder in the crystal lattice. As a result, solids can take on tasks that electrons are unable to perform. These are particularly important in the area of energy conversion and storage as well as environmental protection. In times of climate change and resource conservation, they are of outstanding practical […] Read more.
