Abstract: Strain engineering can enhance oxygen transport in cathodes in solid oxide fuel cells. Here, atomic scale imaging is used to probe local structures in tensile- and compressive-strained La0.6Sr0.4CoO3-δ films, revealing higher oxygen vacancy concentration in tensile films, and vacancy ordering.
