Thin Films and Surface Conductivity

An equally counterintuitive finding is that the interface between two insulating dielectric perovskite oxides, LaAlOj and SrTiOj, can be superconducting. The interface supports a metallic electron gas, and it is this that forms the superconducting state, with a superconducting transition temperature of approximately 2(X)mK for interfaces of thickness of the order of lOnm.
