Charge Transfer in Iridate-Manganite Superlattices

Charge transfer in superlattices consisting of SrIrO_3and SrMnO_3is investigated using density functional theory. Despite the nearly identical work function and non-polar interfaces between SrIrO_3and SrMnO_3 rather large charge transfer was experimentally reported at the interface between them. Here, we report a microscopic model that captures the mechanism behind this phenomenon, providing a qualitative understanding of the...
