LuTe
LuTe is a thermodynamically stable metallic compound consisting of lutetium and tellurium.
About LuTe
LuTe is a metallic compound formed from the rare-earth element lutetium and the chalcogen tellurium. As a thermodynamically stable phase located on the convex hull, it represents a robust chemical configuration that maintains structural integrity under standard conditions.
The compound is characterized by its metallic electronic nature, which distinguishes it from insulating or semiconducting rare-earth chalcogenides. Its high degree of structural variety, evidenced by numerous reported configurations across major databases, makes it a subject of interest for fundamental studies in solid-state chemistry and materials science.
Key Properties
Cross-validated computational properties for LuTe, 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 LuTe. Tight agreement means computed properties can be trusted without re-running calculations.
