## Description

- description: La0.6Sr0.4CoO3 膜の表面構造を、真空下および電気化学条件下で表面X線回折を用いて調べた。 未処理の試料では、表面に二単位格子厚の強く分極した
    SrCoO3層が存在し、表面終端は主に頂点酸素原子をもつ CoO2層であった。 電気化学処理後には、表面は追加の稜共有型 CoO6 二重層で覆われた。 SrCoO3領域での分極は大幅に低下した。
    これらの構造変化は作用電極電流の増加を伴い、表面構造の変調と触媒活性との間に強い関係があることを示唆している。 膜の電位によって誘起される可逆的な構造変調も観察され、これは原子レベルで定性的に理解された。
