Caption: Making a superconductor. Researchers with a molecular beam epitaxy unit used to create a high- temperature superconductor. A research team used the epitaxy unit to deposit eight sequential layers, each one molecule thick, of a cuprate compound into a single crystal containing bismuth, strontium, calcium and oxygen. It was found that this new material has a critical temperature (Tc) of 250 Kelvin (-23 Celsius), below which it is superconducting. This is 117 Kelvin warmer than the previous record. The team, known as UPR5, is at the French National Centre for Scientific Research (CNRS), near Paris, 1993.
