Superconductivity Induced by Electric Field

摘要

New superconductors have so far been discovered by chemical doping in an insulator. We demonstrated for the first time that an electrrostatic charge carrier doping can induce superconductivity. It was performed by the application of a few volts to a SrTi03 through a self-organized electric double layer. This method will provide a new pathway for the future search of novel high-temperature superconductors.
