Scientists discover superconducting interface between two insulators

Researchers at the Cornell University along with some European colleagues have discovered a superconducting phase at the atomic interface of two oxygen-based compounds by exposing them to the extremely cold temperatures close to absolute zero.

Superconductors are elements that can conduct electricity with virtually no resistance at all. These elements are also important because conduction electricity through them minimizes energy loss hence the transmission is made more efficient.

These two oxygen-based compounds or oxides are - Lanthanum Aluminate and Strontium Titanate. The most amazing fact discovered by the scientists is that these two compounds are good insulators, or poor conductors, of electricity. Scientists were amazed to discover that the interface of two insulators was a superconductor. These researchers have also stated that -

"It would be a bit like sticking together two different flavors of Wonder Bread and finding that it made its own chocolate raspberry truffle jam.'
