We demonstrated selective fluorination of a SrFeO2.5 layer in a SrFeO2.5/SrRuO3 epitaxial bilayer film via a topotactic reaction with polyvinylidene difluoride while maintaining the epitaxial relationship. Physical property measurements of the SrFeO2F/SrRuO3 heterostructure confirmed that the SrRuO3 layer could work as a good bottom electrode.
我们通过与聚偏二氟乙烯的拓扑反应，在 SrFeO2.5/SrRuO3 外延双层膜中选择性地氟化 SrFeO2.5 层，同时保持外延关系。SrFeO2F/SrRuO3 异质结构的物理性质测量证实，SrRuO3 层可以作为良好的底电极。
