Abstract

Raman spectroscopy and synchrotron angle-dispersive X-ray diffraction were applied to investigate pressure-induced phase transitions in lithium sulfide (Li2S). We observed two reversible transitions, first from the cubic antifluorite (Fm3¯m) phase to an orthorhombic anticotunnite (Pnma) phase at about 13 GPa, followed by a transition to the hexagonal Ni2In-type (P63/mmc) structure above 30 GPa, as previously predicted by ab initio density functional theory calculations.
