LK99's study, led by Hyun-Tak Kim, presents evidence of superconductivity in PCPOSOS, a potential room-temperature superconductor. They provide raw data and videos to support their findings and invite constructive discussions. The team plans to continue improving their production and testing methods for PCPOSOS.

In recent years, the search for room-temperature superconductors (RTSC) has been a topic of great interest in the scientific community. The potential of RTSC to revolutionize various fields, such as energy transmission and quantum computing, has driven researchers to push the boundaries of traditional superconductivity research. One of the key players in this field is the LK99 team, led by Hyun-Tak Kim, who has been working on the research for PCPOSOS (Pb10−xCux[P(O1−ySy)4]6O1−zSz) for over 10 years.

PCPOSOS, which has the chemical formula x= 3~6, y+z=0.3 ~ 0.4, has been predicted by DFT simulation to exhibit superconductivity. However, previous attempts to replicate this compound have resulted in the production of PCPOO (Pb10−xCux(PO4)O) (x= 0.9~1.1), which is an insulator. It was not until recently that some research groups in China discovered a potential Meissner effect in PCPOSOS.

In their latest paper, Kim and his team present a specific critical temperature for PCPOSOS, demonstrating consistency with the original authors' data. They focused on studying the phase transition of the compound at different temperatures, a crucial evidence of superconductivity. The results showed that each sample exhibited zero resistance and superconductor-conductor phase transitions, with zero resistance values and critical temperatures clearly matching the data provided by the original authors. In order to provide further evidence and transparency, the team also released the raw data and videos of the zero resistance and temperature-dependent measurements publicly available online. They plan to sequentially disclose XRD analysis, SQUID M vs H Meissner effect, and critical current data in future papers.

Despite the skepticism and criticism the team has faced, they remain committed to their research and improvement. They welcome constructive discussions and questions regarding their samples and data. Moreover, they firmly believe that a scholarly mindset entails a critical attitude and it is important to distinguish between skepticism and denial in order to uncover the truth. One of the ways they aim to improve their production process is by constantly studying and replicating PCPOSOS, as well as incorporating advanced techniques such as XRD analysis and SQUID M vs H Meissner effect.

As a part of their efforts to promote transparency and understanding, the team has also shared several videos of their experiments, including the production process and a new partial levitation video. They hope that these videos will provide a better understanding of their research and the potential of PCPOSOS as a room-temperature superconductor.

In conclusion, the LK99 team's latest study on PCPOSOS sheds light on the potential of this compound as a room-temperature superconductor. Their findings, supported by raw data and videos, demonstrate the superconductivity of PCPOSOS and further validate its potential for various applications.
