Ba1Mg2Sr1
Ba1Mg2Sr1 is a metastable, semimetallic intermetallic compound formed from barium, magnesium, and strontium.
About Ba1Mg2Sr1
Ba1Mg2Sr1 is an intermetallic compound composed of barium, magnesium, and strontium. It exhibits a semimetallic electronic character, placing it in a regime where conductive properties are highly sensitive to its precise atomic arrangement.
Due to its position above the thermodynamic hull, this material is considered metastable. Its existence across multiple reported structural configurations highlights the complexity of phase formation in alkaline-earth metal alloys.
Key Properties
Cross-validated computational properties for Ba1Mg2Sr1, aggregated across 2 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.
