In a single film, several physicists from the Brookhaven laboratory in New York have developed the thinnest superconductor at high temperature. Complex copper oxide film. And besides making the film, they have seen that inside the superconductivity occurs in monoatomic planes.

To understand its operation, the film joins an insulating layer. In this system, the phenomenon of superconductivity occurs at the interface at which both layers come into contact.

On the other hand, it has been proven that conductivity is lost by adding zinc throughout the film. In fact, zinc cuts off superconductivity. However, they have seen that, although it only gets into insulating zinc, it affects superconductivity. Although it enters a plane away from the interface, the superconductivity temperature drops from 32K to 18K. Therefore, superconductivity occurs on a single plane, but it is also affected by the environment.
