Abstract
Charge transfer in superlattices consisting of SrIrO$_3$ and SrMnO$_3$ is investigated using density functional theory.
Despite the nearly identical work function and non-polar interfaces between SrIrO$_3$ and SrMnO$_3$, rather large charge transfer was experimentally reported between them.
Our results provide a qualitative understanding to such experimental reports.
We further develop a microscopic model that captures the mechanism behind this phenomenon.
This leads to unique strain dependence of such charge transfer in iridate-manganite superlattices.
The predicted behavior is consistently verified by experiment.
Our work thus demonstrates a new route to control electronic states in non-polar oxide heterostructures.
