Rb2Te5
Rb2Te5 is a semiconducting telluride compound that exists in a metastable state, serving as a subject of interest for structural and synthetic materials research.
About Rb2Te5
Rb2Te5 is a complex telluride compound characterized by its semiconducting electronic behavior. As a member of the alkali metal-telluride family, it represents a unique structural arrangement that has been documented across multiple materials databases, highlighting its significance in synthetic chemistry and fundamental solid-state studies.
Despite its existence in various structural forms, the compound is identified as being thermodynamically above the hull. This metastability suggests that while it can be synthesized and studied under specific laboratory conditions, it occupies a distinct energetic position relative to its elemental constituents.
Key Properties
Cross-validated computational properties for Rb2Te5, aggregated across 5 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.
