“魔角”石墨烯中发现非常规超导关键证据

Core Insights - The research from MIT physicists provides crucial evidence for unconventional superconductivity in twisted trilayer graphene (MATTG), advancing the goal of achieving room-temperature superconductivity [1][2] - Room-temperature superconductivity could lead to innovations such as zero-energy transmission cables, efficient power grids, and practical quantum computing systems [1] Group 1: Research Findings - MATTG exhibits unique quantum properties due to its specific twisting angle, which has led to the emergence of a new research field known as "twisted electronics" [1] - The recent experiments combined electron tunneling measurements with electrical transport tests, revealing a superconducting energy gap only when the material is in a zero-resistance state [1] - Further temperature and magnetic field tests indicated a distinct "V"-shaped curve for the energy gap in MATTG, contrasting with the smooth, symmetric shape typically seen in conventional superconductors [2] Group 2: Implications for Future Research - The findings suggest that the electron pairing mechanism in MATTG differs fundamentally from traditional superconductors, potentially due to strong electron interactions rather than lattice vibrations [2] - The new experimental platform allows real-time observation of the formation and evolution of superconducting energy gaps in two-dimensional materials, providing a novel method for studying electron pairing mechanisms [2] - Future research will explore more twisted structures and materials, aiming to uncover the essence of electron pairing and quantum state competition, which could inform the design of new efficient superconductors and quantum computing materials [2]
