Metallic states in Pb$_{10}$(PO$_4$)$_6$O induced by the Cu/O-insertions and carrier dopingThe reports of room-temperature superconductivity in Cu-doped Pb-apatite draw intense interests and debates. Herein, based on the density functional theory, we show that the Cu-insertion in Pb-apatite is thermodynamically stable and further carrier doping can convert the system CuPb$_{10}$(PO$_4$)$_6$O into metal. The electric conduction is mainly along the one-dimensional (1D) Cu-O chains in the c-axis (out-of-plane). The calculated conductance along the c-axis is larger than the in-plane ones by 2 magnitude orders, indicating the 1D conduction behavior. Moreover, the 1D Cu-O chain is an anti-ferromagnetic Mott insulator at zero-doping point due to the super-exchange. Further electron/hole-doping will erase the anti-ferromagnetism. Therefore, the Cu-inserted system CuPb$_{10}$(PO$_4$)$_6$O show transport and magnetic features similar to the cuprate superconductors. On the other hand, the O-insertion can also induce the metallic states, in which the conductance along the out-of-plane direction is higher than the in-plane direction by 6-folds. Our results display the metallization of Pb$_{10}$(PO$_4$)$_6$O via Cu/O-insertions, and suggesting the electric conductions along the c-axis might dominate the transport behaviors.arxiv.org

요약


베이징 대학교가 황화구리 70% 함유된 걸 LK-99라고 실험해서 황화구리 특성이라고 했더라?


황화구리 순수 샘플 데이터랑도 크게 차이나는데 LK-99 = 황화구리가 말이 된다고 보냐? 니네 그게 말이 된다고 생각해?


니네 말대로 황화구리가 LK-99에 어느정도 영향 끼치는건 맞는거같은데 LK-99 특성이 전부 황화구리에서 나타나는 특성은 아니다


이건 1차원 구조로 이해해야 하고, 구리원자 1D 자기구조이론으로 바라봐야 LK-99의 자기적 특성을 전부 설명할 수 있다


베이징대학교 이 새끼들아 황화구리 좀 그만 떠들고 1차원 특성에 주목해라


끝.
