BaCa3O4
BaCa3O4 is a semiconducting barium-calcium oxide that exists in a metastable state and is primarily of interest for fundamental materials research.
About BaCa3O4
BaCa3O4 is an oxide compound composed of barium, calcium, and oxygen. As a semiconducting material, it represents a complex arrangement of alkaline earth metals that has been documented across multiple structural databases. Its electronic character suggests potential utility in specialized electronic or optoelectronic applications where specific band structures are required. Given its position above the thermodynamic hull, this compound is considered metastable under standard conditions. This status highlights the importance of precise synthesis techniques to stabilize its structure for experimental investigation and potential integration into functional devices.
Key Properties
Cross-validated computational properties for BaCa3O4, 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.
