Proton conduction and nanoionics

This proposal aims towards fundamental and theoretical understanding of the ionic conduction mechanisms in solid oxides. It focuses on defect related properties and on nanosized structures with high interfacial density. Ionic, protonic and electronic defects is considered and special emphasis is directed towards the proton conduction mechanism. The project combines first-principles electronic structure methods with statistical thermodynamics modeling techniques and collaborate closely with experimental groups. More specifically, the project aims are: i) to reveal the fundamental reason for the high grain boundary resistance for proton conduction in perovskites that severely limits the materials performance, ii) to understand how strain, coherency and interfacial chemistry combine to modify defect properties and the proton conduction mechanism in thin films and in heterostructures. The ultimate goal of this research initiative is to contribute to the design of advanced energy relevant material based on the achieved understanding of the fundamental mechanisms operating in these systems.
