Compression-Induced Superconducting Phases
Using megabar-scale pressure in diamond anvil cells to stabilise hydrogen-rich and other dense phases that superconduct at temperatures unreachable at ambient conditions, mapping the ceiling of phonon-mediated pairing.
Developed mainly in: China and United StatesImpacting: North America, Europe and China
A team led by Canfield and Bud'ko (Ames Laboratory/Iowa State, with collaborators in Brazil and at synchrotron facilities) compressed ReO3 to 80 GPa, tracking structural changes by X-ray diffraction and Raman. A rhombohedral R-3c phase hosts bulk superconductivity with onset Tc around 17.5 K; DFT attributes it to strong electron-phonon coupling from Re and oxygen modes.
