MgPbSr2
MgPbSr2 is a semimetallic ternary intermetallic compound composed of magnesium, lead, and strontium that is typically found in a metastable state.
About MgPbSr2
MgPbSr2 is a complex ternary intermetallic compound composed of magnesium, lead, and strontium. It exhibits a semimetallic electronic character, placing it in a unique regime where its electrical properties are highly sensitive to its specific atomic arrangement.
Given its position above the thermodynamic hull, this material is considered metastable or unstable under standard conditions. Despite this, the compound has been documented across multiple structural databases, highlighting its significance in fundamental studies of ternary systems and phase stability.
Key Properties
Cross-validated computational properties for MgPbSr2, 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.
