Ba2U2O7
Ba2U2O7 is a stable, semiconducting barium uranium oxide used in fundamental materials science research.
About Ba2U2O7
Ba2U2O7 is a complex oxide featuring barium and uranium, characterized by its semiconducting electronic nature. As a thermodynamically stable phase residing on the convex hull, it represents a robust configuration within its chemical system.
Its structural reliability is evidenced by multiple reported entries across major materials databases. This stability makes it a significant subject for researchers investigating the interplay between heavy metal cations and oxygen coordination in solid-state chemistry.
Key Properties
Cross-validated computational properties for Ba2U2O7, 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.
