Ca1Pb2Y1
Ca1Pb2Y1 is a metastable ternary intermetallic compound characterized by semimetallic electronic properties and diverse structural arrangements.
About Ca1Pb2Y1
Ca1Pb2Y1 is a ternary intermetallic compound composed of calcium, lead, and yttrium. It exhibits semimetallic electronic characteristics, suggesting a narrow range of charge carrier behavior that is typical of complex metallic alloys.
Due to its position above the thermodynamic hull, this material is considered metastable, which explains the significant number of reported structural configurations. Its complex composition makes it a subject of interest for researchers studying phase stability and structural polymorphism in multi-element metallic systems.
Key Properties
Cross-validated computational properties for Ca1Pb2Y1, 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.
