The German team produced a crystal of pure LK-99 and tested it. From the article:
> LK-99 is not a superconductor, but an insulator with a resistance in the millions of ohms
And furthermore, the graphs from the original pre-print article are just graphs of the resistivity of Cu2S.
It sounds like there's nearly zero chance of any further science here (beyond confirmation).
- postalrat 3y agoA pure crystal of lk-99 is about as useful as a pure crystal of cake.
- ricardobeat 3y agoThe point is that the original team did not produce a pure crystal, and impurities can be the source of novel properties in a material - you’ll know it as “doping” in the semiconductor industry. Other comments from more informed people indicate it’s unlikely that this will yield anything useful though.
- fouc 3y agoSeems like there's a chance the preprint for LK-99 described the material wrongly, so it was not accurately replicated.
- gfodor 3y ago"A crystal of pure LK-99" is an oxymoron, LK-99, the physical substance in Korea, is not a pure crystal.
