LaSF
LaSF is a thermodynamically stable semiconducting material composed of lanthanum, sulfur, and fluorine.
About LaSF
LaSF is a semiconducting compound composed of lanthanum, sulfur, and fluorine. As a thermodynamically stable phase residing on the convex hull, it represents a robust configuration of these elements that maintains structural integrity under standard conditions.
The material is characterized by its distinct electronic properties, which position it as a subject of interest for fundamental studies in inorganic chemistry. Its stability and semiconducting nature make it a valuable candidate for exploring new functional materials within the broader landscape of lanthanum-based chalcogenides and halides.
Key Properties
Cross-validated computational properties for LaSF, 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.
