A paper published on Archiv.org reports that researchers from the Quantum Energy Research Centre, and Korea University, both in Seoul, South Korea have achieved superconductivity at room temperature at ambient pressure, something that has not been achieved before.
The title of the paper is “The First Room-Temperature Ambient-Pressure Superconductor”
The authors are Sukbae Lee, Ji-Hoon Kim, and Young-Wan Kwon/
Here is an excerpt from the introduction to the paper:
For the first time in the world, we report the success in synthesizing a room-temperature and ambient-pressure superconductor with a chemical approach to solve the temperature and pressure problem. We named the first room temperature and ambient pressure superconductor LK-99. The superconductivity of LK-99 proved with the Critical temperature (Tc), Zero-resistivity, Critical current (Ic), Critical magnetic field (Hc), and Meissner effect(14, 15). Several data were collected and analyzed in detail to figure out the puzzle of superconductivity of LK-99: X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Electron Paramagnetic Resonance Spectroscopy (EPR), Heat Capacity, and Superconducting quantum interference device (SQUID) data. Henceforth in this paper, we will report and discuss our new findings including superconducting quantum wells associated with the superconductivity of LK-99.
