Yet another superconductor above 100 K ?

Following the recent discovery of very high temperature conventional superconductivity in sulfur hydride (critical temperature Tc of 203 K). Experimentalist have shown results on the covalent hydride phosphine (PH3) which also exhibits a high Tc > 100 K at pressure P > 200 GPa. However, neither the exact composition nor the crystal structure of the …

Superconductivity under high pressure at minus 70 degrees Celsius

Researchers at the Max Planck Institute for Chemistry in Mainz and the Johannes Gutenberg University Mainz observed that hydrogen sulfide becomes superconductive at minus 70 degree Celsius —when the substance is placed under a pressure of 1.5 million bar. This corresponds to half of the pressure of the earth’s core. With their high pressure experiments …
