Physicists in China have unveiled new clues to the origins of high-temperature superconductivity in an iron-based material just a single unit-cell thick. Led by Qi-Kun Xue and Lili Wang at Tsinghua ...
(a) Crystal structure of the team’s new material. (b) The lengths of repeating unit cells (lattice constants) as a function of iron to nickel ratio. (c) Transition temperatures as a function of iron ...
