(Invited) Role of Chemical Heterogeneities on Oxygen Reduction Kinetics on the Surface of Thin Film Cathodes
We investigated the effects of annealing and A-site stoichiometry on the surface heterostructures at (La0.8Sr0.2)yMnO3 (LSM, y≤1) dense thin films. While annealing at high temperatures induces cation segregation on LSM, A-site deficiency is hypothesized to reduce the level of Sr enrichment on the su...
