  1. Yayoi Takamura, Department of Chemical Engineering and Materials Science, UC Davis, Davis, CA Lattice matched LSAT Tensile strain STO/GSO Compressive strain LAO Superlattices of Perovskite Structured Materials for Solid Oxide Fuel Cells The development of micro- and IT-SOFC’s necessitates the use of thin film electrodes and electrolytes to minimize overall cell resistivity. These thin films experience strains which arise during processing and during operation due to factors such as thermal expansion coefficient differences. Epitaxial thin films serve as a model system for studying the effect of lattice distortions on the conductivity (magnitude and activation energy) of perovskite oxide cathode materials (La1-xSrxMnO3, La1-xSrxFeO3). The nature of the lattice distortion is controlled by the choice of the single crystal oxide substrate.
