Researchers achieve superconductivity at 27K in ultra-thin cobalt compound

Scientists have demonstrated superconductivity in a single-layer cobalt selenide material operating at 27 Kelvin (−246°C) using a chemically treated strontium titanate substrate. The breakthrough could accelerate development of higher-temperature superconductors for power grids, computing, and quantum devices—technologies currently hampered by extreme cooling requirements.
