Ba2Bi3O8Y
Ba2Bi3O8Y is a semimetallic quaternary oxide containing barium, bismuth, oxygen, and yttrium that is currently categorized as a metastable phase.
About Ba2Bi3O8Y
Ba2Bi3O8Y is a complex quaternary oxide composed of barium, bismuth, oxygen, and yttrium. Its electronic character is defined as near-zero-gap, placing it in the semimetallic regime, which makes it a unique candidate for studies involving electronic transport properties.
From a thermodynamic perspective, this material is situated above the hull, suggesting that it is likely unstable under standard conditions. Despite this, it remains a notable subject within materials databases, with multiple reported structural configurations that invite further investigation into its synthesis and potential metastable phases.
Key Properties
Cross-validated computational properties for Ba2Bi3O8Y, 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.
