Anion conductors

Solid ionic conductors (solid electrolytes) are characterized by a high mobility and / or high concentration of ionic defects. They can be classified as weakly disordered materials (low defect concentrations, high mobility) or as heavily disordered "superionic" conductors (high concentration of point defects).

Examples of anion conductors investigated are:

Acceptor-doped ZrO₂ and CeO₂,CaF₂, BaF₂

Heterostructures of anion conductors

Current Projects:

• Interface effects on the electrical conductivity of oxide thin films
• Size effects in nanocrystalline SrTiO₃
