Hydrogen Clathrate Structures in Rare Earth Hydrides at High Pressures: Possible Route to Room-Temperature Superconductivity.

Physical review letters

Peng F, Sun Y, Pickard CJ, Needs RJ, Wu Q, Ma Y.
PMID: 28949166
Phys Rev Lett. 2017 Sep 08;119(10):107001. doi: 10.1103/PhysRevLett.119.107001. Epub 2017 Sep 08.

Room-temperature superconductivity has been a long-held dream and an area of intensive research. Recent experimental findings of superconductivity at 200 K in highly compressed hydrogen (H) sulfides have demonstrated the potential for achieving room-temperature superconductivity in compressed H-rich materials....
