AsNdSe
AsNdSe is a stable, semiconducting ternary compound containing arsenic, neodymium, and selenium.
About AsNdSe
AsNdSe is a ternary semiconducting compound composed of arsenic, neodymium, and selenium. Its position on the convex hull indicates that it is a thermodynamically stable phase, making it a reliable candidate for systematic study in solid-state chemistry.
As a semiconducting material, it holds interest for researchers investigating the interplay between rare-earth elements and pnictogen-chalcogenide frameworks. Its structural diversity, evidenced by multiple reported configurations, suggests a complex landscape for potential electronic or optoelectronic applications.
Key Properties
Cross-validated computational properties for AsNdSe, 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.
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 AsNdSe. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
