LuSe
LuSe is a metallic lutetium selenide compound that is considered stable enough to be synthesized for research purposes.
About LuSe
LuSe is a metallic inorganic compound composed of lutetium and selenium. Its electronic character is defined by a lack of a band gap, placing it firmly within the category of metallic conductors rather than semiconductors or insulators.
Because it sits near the thermodynamic hull, this compound is considered a promising candidate for experimental synthesis. Its structural diversity, evidenced by numerous reported configurations across databases, highlights its significance in fundamental materials science research.
Key Properties
Cross-validated computational properties for LuSe, aggregated across 5 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.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of LuSe. Tight agreement means computed properties can be trusted without re-running calculations.
