Lu2S3
Lu2S3 is a thermodynamically stable semiconducting compound composed of lutetium and sulfur.
About Lu2S3
Lu2S3 is a binary rare-earth sulfide that exhibits semiconducting electronic behavior. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of lutetium and sulfur atoms. Its structural diversity is highlighted by the numerous configurations documented across various materials databases, underscoring its significance in solid-state chemistry.
This compound serves as a critical subject for researchers investigating the electronic and optical properties of heavy lanthanide chalcogenides. Its stability and well-defined semiconducting nature make it a valuable candidate for fundamental studies into how rare-earth elements influence the band structure and lattice dynamics of inorganic sulfides.
Key Properties
Cross-validated computational properties for Lu2S3, aggregated across 3 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.
