At interfaces between complex oxides, electronic systems with unusual electronic properties can be generated. We report on superconductivity in the electron gas formed at the interface between two insulating dielectric perovskite oxides, LaAlO3 and SrTiO3. The behavior of the electron gas is that of a two-dimensional superconductor, confined to a thin sheet at the interface. The superconducting transition temperature of ≅ 200 millikelvin provides a strict upper limit to the thickness of the… Expand

Superconductivity induced by interfacial coupling to magnons
We consider a thin normal metal sandwiched between two ferromagnetic insulators. At the interfaces, the exchange coupling causes electrons within the metal to interact with magnons in the insulators.Expand

Metallic conduction at organic charge-transfer interfaces.
TLDR
Investigation of interfaces between crystals of conjugated organic molecules, which are large-gap undoped semiconductors, that is, essentially insulators, finds that highly conducting interfaces can be realized with resistivity ranging from 1 to 30 kohms per square, and that the temperature dependence of the conductivity is metallic.
