RbCr5S8
RbCr5S8 is a stable, semiconducting ternary sulfide containing rubidium and chromium.
About RbCr5S8
RbCr5S8 is a complex ternary sulfide composed of rubidium, chromium, and sulfur. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that maintains structural integrity under standard conditions. The material exhibits semiconducting electronic character, making it an interesting candidate for research into the interplay between transition metal d-orbitals and chalcogenide frameworks. Its structural diversity is highlighted by multiple reported configurations across various materials databases.
Key Properties
Cross-validated computational properties for RbCr5S8, 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.
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.
