Abstract

The effect of crystal orientation on aliovalent dopant segregation at the surface of La<sub>0.6</sub>Sr<sub>0.4</sub>CoO<sub>3</sub> as a model perovskite oxide was investigated. Statistical evaluation of SEM-EBSD images revealed that the area coverage of precipitates on grains having orientations close to {001} is more than three times higher compared to that on other orientations.
