Prediction of Room‐Temperature Superconductivity in Quasi‐Atomic H2‐Type Hydrides at High Pressure

AbstractAchieving superconductivity at room temperature (RT) is a holy grail in physics. Recent discoveries on high‐Tcsuperconductivity in binary hydrides H3S and LaH10at high pressure have directed the search for RT superconductors to compress hydrides with conventional electron–phonon mechanisms. Here, an exceptional family of superhydrides is predicated under high pressures,MH12(M= Mg, Sc, Zr, Hf, Lu), all exhibiting RT superconductivity with calculatedTcsranging from 313 to 398 K. In contrast to H3S and LaH10, the hydrogen sublattice inMH12is arranged as quasi‐atomic H2units. This unique configuration is closely associated with highTc, attributed to the high electronic density of states derived from H2antibonding states at the Fermi level and the strong electron–phonon coupling related to the bending vibration of H2and H‐M‐H. Notably, MgH12and ScH12remain dynamically stable even at pressure below 100 GPa. The findings offer crucial insights into achieving RT superconductivity and pave the way for innovative directions in experimental research.
