LuSeF is a metastable semiconducting compound composed of lutetium, selenium, and fluorine.

About LuSeF
LuSeF is a complex inorganic compound characterized by its semiconducting electronic nature. As a metastable material, it represents a synthetic challenge, existing in a delicate state that requires precise control during formation to achieve structural integrity. Its composition of rare-earth lutetium paired with selenium and fluorine positions it as a specialized candidate for fundamental materials research. Because of its unique elemental combination, it serves as an intriguing subject for exploring the interplay between heavy rare-earth elements and chalcogenide-halide frameworks. Its existence across multiple databases highlights its role as a documented, albeit rare, phase in solid-state chemistry.
Key Properties
Cross-validated computational properties for LuSeF, 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.
