Rb2V4O9
Rb2V4O9 is a semimetallic rubidium vanadium oxide that is considered thermodynamically stable enough to be synthesized for experimental study.
About Rb2V4O9
Rb2V4O9 is a complex vanadium oxide characterized by its near-zero-gap electronic structure, placing it in the category of semimetallic materials. Its composition suggests a unique arrangement of vanadium and oxygen polyhedra balanced by rubidium cations, which influences its electronic behavior and structural integrity.
As a material identified as being near the thermodynamic hull, it is considered a likely candidate for successful laboratory synthesis. The existence of multiple reported structures across various databases underscores its significance as a subject of ongoing investigation in solid-state chemistry.
Key Properties
Cross-validated computational properties for Rb2V4O9, 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.
