Rh1Sc2Zn1
Rh1Sc2Zn1 is a semiconducting ternary intermetallic compound belonging to the platinum-group alloy family.
About Rh1Sc2Zn1
Rh1Sc2Zn1 is a complex ternary intermetallic compound categorized within the platinum-group alloy catalyst class. Characterized by a semiconducting electronic profile, it represents a unique intersection of transition metal and rare-earth chemistry that is of significant interest for fundamental materials research.
While this phase exhibits a high degree of structural diversity with numerous reported configurations, it is identified as being thermodynamically above the hull. This suggests that the material is inherently unstable under standard conditions, positioning it as a subject for specialized synthesis studies rather than bulk industrial application.
Key Properties
Cross-validated computational properties for Rh1Sc2Zn1, aggregated across 2 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 platinum-group alloy catalysts class.
Within the broader class of platinum-group alloys, Rh1Sc2Zn1 exhibits distinct electronic behavior compared to more conventional metallic conductors like LaRh or BaPd. While many members of this class are optimized for high-stability catalytic performance, Rh1Sc2Zn1 is notable for its semiconducting nature, which sets it apart from the typical metallic character found in siblings such as GeRu or Ga2Ru.
