Decomposition Products of Phosphine Under Pressure: PH2 Stable and Superconducting?

TL;DR: The results suggest that the superconductivity recently observed by Drozdov, Eremets, and Troyan when phosphine was subject to pressures of 207 GPa in a diamond anvil cell may result from these, and other, decomposition products of phosphine.
Journal ArticleDOI

Polyhydrides of the Alkaline Earth Metals: A Look at the Extremes under Pressure

TL;DR: The most stable stoichiometries and structures of beryllium and barium polyhydrides, MHn with n > 2 and M = Be/Ba, under pressure were predicted in this article.
Journal ArticleDOI

Composition and Constitution of Compressed Strontium Polyhydrides

TL;DR: In this article, the structure of strontium polyhydrides with n > 2 was studied using evolutionary algorithms coupled with density functional theory calculations, and a number of phases with even n were found to be thermodynamically stable below 150 GPa.

Decomposition Products of Phosphine Under Pressure: PH2 Stable and Superconducting?

TL;DR: In this article, three metallic PH2 phases were found to be dynamically stable and superconducting between 100-200 GPa, and their critical temperatures were computed as being 70 and 76 K, respectively, via the Allen-Dynes modified McMillan formula.
