A Dream of Room-temperature Superconductors

Abstract
In this talk, I will talk about the discovery of a room-temperature ambient-pressure superconductor recently announced by a Korean research team: LK-99, which caused excitement and scientific sensation worldwide. Then I will briefly give an introduction to superconductivity, including the characteristics of superconductors, development history, the searching for new superconductors, and the applications of superconductors. Finally, I will present our experimental results for verifying the LK-99, giving the conclusion that LK-99 is classified as a diamagnetic semiconductor.
