LuS
LuS is a thermodynamically stable metallic compound consisting of lutetium and sulfur.
About LuS
LuS is a binary metallic compound formed from lutetium and sulfur. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement that persists under standard conditions.
The material is characterized by its metallic electronic nature, distinguishing it from typical insulating or semiconducting rare-earth sulfides. With numerous reported structures across major databases, it serves as a significant subject for studies in solid-state chemistry and materials science.
Key Properties
Cross-validated computational properties for LuS, aggregated across 4 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
