Superconductivity Society Verification Committee: "No Evidence at All That LK-99 Is a Superconductor"

"LK-99, Rather an Insulator with High Resistivity Value"

The Korean Superconductivity and Cryogenics Society Verification Committee stated that there is "no evidence at all" that 'LK-99,' which domestic researchers claimed to be a room-temperature and ambient-pressure superconductor, is indeed such a material.

On the 13th, the Verification Committee released the 'LK-99 Verification White Paper' and made this announcement. According to the white paper, reproduction studies conducted by eight domestic research institutes following the methods presented by the authors of LK-99-related papers showed no superconductivity at either room temperature or low temperatures.

The Verification Committee said, "No cases showed zero resistance and the Meissner effect in domestic and international reproduction experiments," adding, "Most results indicate that LK-99 is rather an insulator with a very high resistivity."

The verification involved eight domestic research institutions: the Materials Convergence Measurement Research Center at the Korea Research Institute of Standards and Science, the Quantum Materials Laboratory at Pusan National University, the Electronic Active Energy Laboratory at Sungkyunkwan University, the Energy Materials Quantum Properties Laboratory at Kyung Hee University, the Advanced Complex Materials State Research Group at Seoul National University, the High Pressure Physics Laboratory at Hanyang University, the Quantum Materials Superconductivity Laboratory at Sungkyunkwan University, and the Department of Physics at Pohang University of Science and Technology.

Superconductivity refers to a state where electrical resistance becomes zero. Electrical resistance gradually decreases as temperature drops and completely disappears at a certain temperature. When electrical resistance vanishes, electricity can be transmitted without energy loss, potentially causing a revolutionary change in energy utilization. This is why LK-99 attracted significant attention from the scientific community.
