WebMar 26, 2024 · In contrast, the average B-site ion valence (v 0) decreased from 3.40 to 3.32 (for LSCrF and ex-LSCrFRu 1.0 h, Table S3). The decrease in the lattice oxygen was attributed to the exsolution of the Ru element from the B-site in perovskite crystalline structure, accompanied by B-site defects. Webmanipulation of oxygen ion transport in the electrolyte may be greatly affected by local strain elds in addition to the extrinsic doping level. Such an effect would be comparable to current investigations in heterolayers where strain elds are generated intentionally through interface modulations in oxygen ion conductors, e.g. ref. 15 and 53.
