The material is characterized by significant structural diversity, with multiple documented configurations across various databases. This structural richness makes it a subject of interest for researchers investigating the interplay between alkali metals, rare-earth elements, and chalcogens in solid-state chemistry.
Key Properties
Cross-validated computational properties for RbYS2, 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.
