About Pb1Sr2Zn1
Pb1Sr2Zn1 is a complex intermetallic compound composed of lead, strontium, and zinc. As a semiconducting material, it occupies a unique electronic niche that distinguishes it from purely metallic alloys, making it a subject of interest for fundamental solid-state research.
Because it is classified as a near-hull phase, this compound is considered thermodynamically accessible and likely synthesizable under controlled conditions. Its existence within structural databases highlights its role as a candidate material for exploring new phase spaces in ternary intermetallic systems.
Key Properties
Cross-validated computational properties for Pb1Sr2Zn1, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
