LaTe2
LaTe2 is a thermodynamically stable, semimetallic lanthanum telluride compound used primarily in advanced materials research.
About LaTe2
LaTe2 is a stable lanthanum telluride compound characterized by its near-zero-gap electronic structure. As a semimetallic material, it exhibits unique charge carrier dynamics that distinguish it from traditional wide-gap semiconductors or metallic conductors.
Its thermodynamic stability on the convex hull makes it a robust candidate for fundamental studies in condensed matter physics. Researchers utilize this compound to explore the interplay between rare-earth magnetism and chalcogenide-based electronic transport.
Key Properties
Cross-validated computational properties for LaTe2, aggregated across 6 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.
