RhS2
RhS2 is a metastable metallic sulfide that has been extensively documented for its diverse structural configurations.
About RhS2
RhS2 is a metallic sulfide characterized by its lack of a band gap, placing it firmly within the category of conductive inorganic materials. Despite its metastable nature, it has been the subject of significant structural investigation, as evidenced by the large body of reported crystallographic data available across multiple databases. Its electronic behavior makes it a compelling candidate for studies involving transition metal chalcogenides where metallic conductivity is a primary requirement. The compound's ability to adopt various structural configurations highlights the complexity of rhodium-sulfur bonding environments. This diversity in structural arrangements suggests that RhS2 serves as a versatile platform for exploring phase stability and the influence of synthesis conditions on material properties.
Key Properties
Cross-validated computational properties for RhS2, 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.
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 RhS2. Tight agreement means computed properties can be trusted without re-running calculations.
