According to Fudan University, high-temperature superconductivity is an important direction for the future development of efficient power transmission and high-performance electronic devices, but its micromechanism has always been the “crown mystery” of condensed matter physics. On the evening of August 12, Beijing time, Professor Zhang Yuanbo of the Department of Physics at Fudan University and his collaborators published research results in “Nature” under the title “Supercharged 2D cuprate with a single CuO₂ plane”, successfully thinning copper-based high-temperature superconductors to contain only one superconducting plane — that is, a single CuO₂ surface. This “extreme operation” not only confirmed the two-dimensional nature of high-temperature superconductivity, but also discovered strange “abnormal metal states” and quantum critical phenomena at the critical point of the superconductor-insulator transition, providing a new quantum experimental platform for studying the mechanism of high-temperature superconductivity.
