NdSe2
NdSe2 is a thermodynamically stable, metallic neodymium selenide compound.
About NdSe2
NdSe2 is a metallic neodymium selenide that occupies a stable position on the thermodynamic convex hull. Its electronic character suggests significant potential for applications requiring conductive chalcogenide frameworks, supported by its presence across multiple structural databases.
As a material characterized by its structural diversity, NdSe2 serves as an important subject for studying rare-earth selenide systems. Its inherent stability makes it a reliable candidate for further investigation into electronic and magnetic behaviors in the solid state.
Key Properties
Cross-validated computational properties for NdSe2, 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 NdSe2. Tight agreement means computed properties can be trusted without re-running calculations.
