I am not a scientist but I have really been trying to understand this breakthrough. My understanding is not that room temperature ambient pressure semiconductors have been created. It is that several simulations back up parts of the discovery that would lead to said semiconductors, in some reviews are showing that some of the crystalline structures do successfully resemble what would be needed for superconductivity in super preliminary experiments on a tiny scale. We aren’t going to have magic superconducting wire yet, this is still very much in the theoretical material science phase. Ultimately, specifics around the way the doping has to work are pretty unproven. At this point it looks like things like electron photon interaction is happening as it would need to happen on a scale relevant to similar crystalline structures. LK99 isn’t yet in physical testing in any other labs yet, and any labs that would publish results already wouldn’t be worth listening to because there hasn’t been enough time for peer review.
