YbTe
ytterbium telluride
Ytterbium telluride is a thermodynamically stable semiconducting material composed of ytterbium and tellurium.
About ytterbium telluride
Ytterbium telluride is a stable binary chalcogenide that exhibits semiconducting behavior. Its position on the convex hull indicates a robust thermodynamic state, making it a reliable subject for fundamental materials research.
With multiple documented structural variations across scientific databases, this compound serves as a significant model for studying rare-earth tellurides. Its electronic character is defined by its semiconducting nature, which is central to its utility in specialized optoelectronic and solid-state applications.
Key Properties
Cross-validated computational properties for ytterbium telluride, 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 YbTe. 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.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
