Ca2Pb
Ca2Pb is a stable semiconducting intermetallic compound composed of calcium and lead.
About Ca2Pb
Ca2Pb is a thermodynamically stable intermetallic compound that sits firmly on the convex hull, indicating significant structural robustness. As a semiconducting material, it offers a unique electronic profile that distinguishes it from purely metallic alloys within the calcium-lead system.
Its structural complexity is evidenced by the extensive number of reported crystal configurations across multiple databases. This diversity in structural arrangements makes it a subject of interest for researchers investigating the fundamental relationships between atomic packing and electronic behavior in binary intermetallics.
Key Properties
Cross-validated computational properties for Ca2Pb, 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.
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.

How It Compares
As a distinct binary phase, Ca2Pb serves as a primary reference point for understanding the interplay between alkaline earth metals and heavy p-block elements. Without direct structural siblings in this specific class, it stands as a standalone example of how stoichiometry dictates stability and semiconducting character in calcium-lead systems.
