Ba1Li2Pb1
Ba1Li2Pb1 is a semiconducting ternary intermetallic compound containing barium, lithium, and lead that is characterized by its metastable nature.
About Ba1Li2Pb1
Ba1Li2Pb1 is a ternary intermetallic compound composed of barium, lithium, and lead. As a semiconducting material, it exhibits distinct electronic characteristics that differentiate it from typical metallic alloys, making it a subject of interest for fundamental solid-state research.
Despite the existence of multiple reported structural variations in crystallographic databases, thermodynamic analysis suggests that this phase resides above the hull. This indicates that the compound is likely metastable or unstable under standard conditions, requiring specific synthesis pathways to achieve formation.
Key Properties
Cross-validated computational properties for Ba1Li2Pb1, 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.
