Additional information

Current great controversy over the effects of interfacial tensile lattice strain: enhancement of ionic conductivity in epitaxial solid electrolytes? High technological impact of enhancement as implies possibility of very low (<400C) temperature electrochemical devices, e.g. SOFCs with substantial cost and durability gains. Previous publications report ambiguous measurements on poorly characterised structures. Collaboration in multitechnique investigation of microstructure-transport relationships. Strain mapped at epitaxial heterointerfaces for first time in electrolyte structures. Tensile strain shown not to enhance ionic conductivity/diffusion in YSZ , no prospect of use in devices. 2 invited talks (Fall MRS and 7th IDMRS) for team members.
