About NaNdS2
NaNdS2 is a ternary sulfide compound composed of sodium, neodymium, and sulfur. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that is well-defined within the chemical space of rare-earth chalcogenides. Its electronic character as a semiconductor makes it a subject of interest for researchers investigating the interplay between rare-earth magnetism and semiconducting behavior. The compound is characterized by a high degree of structural diversity, with multiple reported configurations across various databases, indicating a complex landscape of stable atomic arrangements. This structural richness provides a foundation for exploring its potential in specialized electronic or optical applications where stable, rare-earth-doped materials are required.
Key Properties
Cross-validated computational properties for NaNdS2, aggregated across 3 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.
