NdTe2
NdTe2 is a thermodynamically stable metallic compound composed of neodymium and tellurium.
About NdTe2
NdTe2 is a metallic neodymium telluride compound that holds a position on the thermodynamic convex hull, indicating significant structural stability. Its composition of rare-earth neodymium and chalcogenide tellurium creates a robust lattice arrangement that has been extensively documented across multiple crystallographic databases. As a metallic system, this compound is of particular interest for studying the interplay between localized f-electron magnetism and itinerant conduction electrons. Its stability makes it a reliable candidate for fundamental investigations into rare-earth telluride physics and potential electronic applications.
Key Properties
Cross-validated computational properties for NdTe2, 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.
