This article is about the development of room-temperature superconductivity of the material LK-99, which was achieved through the fabrication of thin films by using microfabrication technology. This development could revolutionize how electronics components and devices are designed, as it opens up a range of new possibilities including the development of more efficient systems and devices, particularly for telecommunications, automotive, and industrial Sectors.

Development of Discrete Elements for Superconducting Electronics (Including SQUIDs) for Room-temperature Operation Enabled by LK99 Thin Films. "We plan to explore superconductivity in the material LK-99 in thin film form using our laboratory deposition and diagnostic facilities. As soon as these films will superconduct at room-temperature, weakly-coupled bridges and more sophisticated discrete superconducting electronics elements will be fabricated and tested." .

The original south korean research work always only claimed that there was superconducting levels of low electrical resistance in thin films of LK99. This was made with chemical vapor deposition. The original peer-reviewed LK99 superconductor paper only briefly mentions the thin film work and measurements. However, this is the most important part because only the chemical vapor deposited thin film has the zero resistance superconducting measurement. Nextbigfuture has said that they researchers on LK99 need to put in a effort to check the thing the korean actually said that they did. I think a few tens of millions should be put into to it to make damn sure about the thin film and to try to check the computational theory adjustments. In August and September 2023, the consensus of other labs was that LK-99 is not a superconductor at any temperature but only bulk non-thin film samples have been made. None of replications have gone through the peer-review process of a journal.

Patent on the LK99 Thin Film Superconductivity .

In the patent, they show and state there is superconducting levels of low resistance. The resistivity of LK-99 was 1/10,000 to 1/100,000 of copper. For Example 4, the grains of the solid phase reaction were processed into a square shape and the resistance change according to the temperature change (304K ~ 382K) was measured using equipment (Power (voltage/current) Source KEITHLEY 228A, Sensitive Digital Voltmeter KEITHLEY 182, Probe Method: Measured using the 4-probe method) and the results are shown in FIG. 29. Referring to this, it can be seen that the ceramic compound according to the present invention exhibits superconductive properties. In addition, FIG. 42 is a photograph of an experiment in which resistance was measured in real time for Example 4, and the measured resistance was approximately 10^-12 Ohms per centimeter. Very low resistance in Ohmcm.Thanks to twitter user @8teAPi for the info on the patent info.

More description of the vapor deposition process that makes the micron(s) thick thin film which is the only material claimed to be superconducting was included. They claim they get 48.9% of the lead apatite thin film as superconductive, plus lead compounds (40%) and Copper compounds (10%). The new description includes some silicon in the process. Lead apatite itself is an insulator and the korean team says they need doping and defects to make it into a superconductor. The superconductor consists of lead apatite of phases with three different critical temperatures of Tc, I~50C, II~80C, III~125C. In thin film, only Tc I, II were seen with resistance measurement. They also say there is diamagnetism and ferromagnetism. Tc I is antiferromagnetic.

The development of room-temperature superconductivity is a significant breakthrough in the world of microelectronics and has the potential to revolutionize how electronics components and devices are designed. Discrete elements for superconducting electronics, such as SQUIDs, can enable greater efficiency and accuracy for measuring and processing signals. For example, these components can be used in the telecommunications industry to reduce signal noise and improve spectral efficiency. The use of microfabrication technology to fabricate thin films of the material LK-99, which was previously known to be a lead-based superconductor at extremely low temperatures, marks the first time that this material has been observed to be superconducting at room temperatures. This development opens up a range of new possibilities for the development of room-temperature superconducting electronics, including the possibility of further development of SQUID devices not just for measuring signals but for actual changing and reinforcing them. Furthermore, these devices could be used to develop new, highly efficient, energy-saving systems and devices for various industries. These developments have potential to be extremely important for the telecommunications, automotive, and industrial sectors, as the research continues to advance and lead to the development of more sophisticated and efficient components.
