rubidium hydride
Rubidium hydride is a stable, semiconducting binary compound formed from rubidium and hydrogen.
About rubidium hydride
Rubidium hydride is a binary compound consisting of rubidium and hydrogen. As a thermodynamically stable material that sits on the convex hull, it represents a robust phase within its chemical system, characterized by its distinct semiconducting electronic nature.
Its structural complexity is evidenced by a significant number of reported configurations across major databases. This diversity in structural arrangements makes it a subject of interest for researchers investigating the fundamental behavior of alkali metal hydrides in various physical environments.
Key Properties
Cross-validated computational properties for rubidium hydride, 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.
