The metallization and superconductivity of dense hydrogen sulfide

Y Li, J Hao, H Liu, Y Li, Y Ma - The Journal of chemical physics, 2014 - pubs.aip.org
Hydrogen sulfide (H 2 S) is a prototype molecular system and a sister molecule of water (H 2
O). The phase diagram of solid H 2 S at high pressures remains largely unexplored arising
from the challenges in dealing with the pressure-induced weakening of S–H bond and
larger atomic core difference between H and S. Metallization is yet achieved for H 2 O, but it
was observed for H 2 S above 96 GPa. However, the metallic structure of H 2 S remains
elusive, greatly impeding the understanding of its metallicity and the potential …
