The First Room-Temperature Ambient-Pressure SuperconductorFor the first time in the world, we succeeded in synthesizing the room-temperature superconductor ($T_c \ge 400$ K, 127$^\circ$C) working at ambient pressure with a modified lead-apatite (LK-99) structure. The superconductivity of LK-99 is proved with the Critical temperature ($T_c$), Zero-resistivity, Critical current ($I_c$), Critical magnetic field ($H_c$), and the Meissner effect. The superconductivity of LK-99 originates from minute structural distortion by a slight volume shrinkage (0.48 %), not by external factors such as temperature and pressure. The shrinkage is caused by Cu$^{2+}$ substitution of Pb$^{2+}$(2) ions in the insulating network of Pb(2)-phosphate and it generates the stress. It concurrently transfers to Pb(1) of the cylindrical column resulting in distortion of the cylindrical column interface, which creates superconducting quantum wells (SQWs) in the interface. The heat capacity results indicated that the new model is suitable for explaining the superconductivity of LK-99. The unique structure of LK-99 that allows the minute distorted structure to be maintained in the interfaces is the most important factor that LK-99 maintains and exhibits superconductivity at room temperatures and ambient pressure.arxiv.org

이게 퀀텀




논문 들어가서 ctrl F로 키워드 검색해봤는데

전자는 thin언급이 9번 나옴(think가 껴있어서 실질적으론 8번)



후자는 thin, film 어떤 키워드로 찾아도 안 나옴



참고로 저기서 thin언급이 나온 유일한 데이터가 영완시치 논문의 b그래픈데

이건 안될과학 걔도 진짜라면 초전도체라고밖에 볼 수 없다고 언급함(다만 그 뒤에 다른 논문과 동일한 샘플인 것으로 보아 재측정이 필요해보인다라고 함. 다른건 저항0이 택도없으니깐)


아마 후자 논문은 아예 박막 내용을 빼버린거고

전자논문은 잉곳+박막내용까지 싹 긁어모아서 넣은듯
