Ru1Sb2Te1 is a semimetallic ruthenium-based alloy that is studied for its unique structural properties within the field of platinum-group catalysts.
About Ru1Sb2Te1
Ru1Sb2Te1 is a complex platinum-group alloy characterized by its semimetallic electronic nature. As a member of this specialized class of materials, it serves as a subject of interest for researchers investigating the influence of ruthenium-based coordination on catalytic efficiency and charge transport properties.
Despite its structural diversity, this compound is identified as being above the thermodynamic hull, suggesting it may be metastable under ambient conditions. Its role in materials science is primarily focused on exploring the boundaries of phase stability within complex pnictide-chalcogenide systems.
Key Properties
Cross-validated computational properties for Ru1Sb2Te1, 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.
