Superconductivity above 100 K in PH3 at high pressures
Abstract
Following the recent discovery of very high temperature conventional superconductivity in sulfur hydride (critical temperature Tc of 203 K, Ref1) we searched for superconductivity in other hydrides and found that a covalent hydride phosphine (PH3) also exhibits a high Tc >100 K at pressure P > 200 GPa as determined from four-probe electrical measurements.
