The formation of two-dimensional electron gases (2DEGs) at complexoxide interfaces is directly influenced by the oxide electronic properties.
2
At interfaces between complexoxides, electronic systems with unusual electronic properties can be generated.
3
Interfaces between complexoxides are emerging as one of the most interesting systems in condensed matter physics.
4
The disorder inherent to doping by cation substitution in the complexoxides can have profound effects on collective-ordered states.

Furthermore, this study provides an avenue for building functional atomic-scale oxide 2D structures and reveals the thin-film growth processes of complexoxides.
