Key Properties
Cross-validated computational properties for DyNiSb, aggregated across 4 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.

How It Compares
Within the skutterudite thermoelectrics class.
Within the diverse family of skutterudite-related compounds, DyNiSb distinguishes itself through its rare-earth composition compared to transition-metal-heavy counterparts like NiP2 or FeP2. While many members of this class focus on pnictide-based frameworks, DyNiSb leverages the unique electronic influence of dysprosium to modify its semiconducting behavior relative to simpler binary phosphides.
