Superconductor On-Off Switch

European scientists show that an electric field can turn on and off superconductivity in a fabricated circuit
Department: Science & Technology

European scientists have demonstrated that an electric field can turn on and off low-temperature superconductivity in a fabricated circuit (Nature 2008, 456, 624). This new capability is expected to lead to nanoscale superconducting (resistance-free) circuits that can be controlled by strategically located electric-field modulators. These scientists previously discovered that at the interface between two layers of oxide insulators, LaAlO3 and SrTiO3, a superconducting "electron gas" forms. Now, Andrea D. Caviglia and
