MIT Discovers Unconventional Superconductivity in Graphene Tri-Layers

11/7/2025

Summary

Story summary

Massachusetts Institute of Technology (MIT) researchers confirmed unconventional superconductivity in magic-angle twisted tri-layer graphene (MATTG).
The material shows a V-shaped gap, indicating a pairing mechanism driven by strong electronic interactions rather than lattice vibrations.
The study, published in Science, used a platform integrating tunneling spectroscopy and electrical transport measurements to observe these properties.
The work could pave the way for room-temperature superconductors and affect energy transmission and quantum computing.

History

Historical Context

In 1986, physicists Johannes Georg Bednorz and Karl Alexander Müller discovered high-temperature superconductivity in lanthanum barium copper oxide, achieving a critical temperature of 35 Kelvin. This breakthrough surpassed previous records and initiated extensive research into unconventional superconductors, including recent studies at MIT on magic-angle twisted tri-layer graphene, which may lead to room-temperature superconductivity and transformative applications in energy transmission and quantum computing.
