Reddit 有人放 Kim Hyeon Tak interview 的內容, 有談到為何原始文件沒放電阻資料
Q. You didn't offer resistivity data so some people wonder if supreconductivity is true.
A. (omitted)We already put resistivity data in earlier paper. So we thought we don't have to insert such data into second paper(which is in arXive)

1. Why wasn't this published as a formal paper?

- There were unavoidable circumstances. We reported it in a journal at the same time.

2. Two papers exist in the archive. Why?

- The authors of the first paper disagreed. The second paper has many authors, and the authors agree, so the first paper is wrong.

3. I heard that the Korean Society for the Verification of Room Temperature Superconductivity requested samples for verification.

- Our team agreed to 'help' the Korean researchers to do their research, but verification is a different matter.

4. Why isn't the resistance zero?

- If the resistance drops discontinuously low in a metal, it is a superconductor, because whether the resistance is zero or not is a matter of noise. I've already written about the presence of noise in experiments in the paper. The question of whether the resistance of a superconducting state is zero or not was debated over 100 years ago. This is a debate that follows every time a superconducting phenomenon is discovered. I had already written in my first paper that there was a discontinuous "jump" and that when I actually measured it, the resistance was zero. So we didn't put it in the second paper. We didn't write it down because we knew it.

5. Why doesn't LK-99 float completely?

- Our sample produces a one-dimensional superconductor, so next to a straight line of superconductor it is a non-metal. When measured, they appear together. We did not make a very uniform sample. So it floats at an angle.

6. No Qeustion

So, even if we develop the technology in the future, it's not going to be as good as a two- or three-dimensional superconductor. But I think we can cut through the first dimension. This is where a lot of technology development is needed. We are just getting started.

7. How did you get involved in this research?

My thesis came out in 2021, and a research institute contacted me that they had made a superconductor. They said they didn't have enough theory, so they reached out to me.

8. How do you recognize a superconductor?

The first way to tell if something is superconducting or not is that there is a "jump".

There is a discontinuous jump between a state with an energy gap and a state without.

In other words, in a metal that is superconducting or not, a jump towards lower resistance is superconducting.

9. There are semiconductors called MIT materials that are not superconductors.

It is an MIT material that jumps to the side where the resistance increases.
