Solving the LK-99 puzzle

Research output: Contribution to journal › Comment/debate › peer-review

Abstract

The claim of room-temperature, ambient-pressure superconductivity in copper-doped lead apatite, LK-99, was both sensational and puzzling. I describe how this puzzle was solved. An entirely different property, superionicity, of a byproduct produced by copper doping was mistaken to be superconductivity.
