Interfacial Processes

Interfacial Processes

At interfaces (grain boundaries, heterocontacts, surfaces) redistribution of defects and thus of charge carriers occurs, leading to strongly modified electrochemical properties. Transport along and across grain boundaries can be affected in a very different manner. Interfacial and surface reactions also involve the defects and are a necessary step of each solid state chemical reaction.

Research Areas:

    • Transport along and across grain boundaries
    • Interfacial storage
    • Solid-solid- and solid-liquid-interactions in composites
    • Solid / gas-interactions for at mixed conductors
