Hg1Pb2Sn1
Hg1Pb2Sn1 is a semiconducting intermetallic material composed of mercury, lead, and tin that exists in a metastable state.
About Hg1Pb2Sn1
Hg1Pb2Sn1 is a complex intermetallic compound composed of mercury, lead, and tin. It exhibits semiconducting electronic behavior, positioning it as an interesting subject for fundamental research into multi-element metallic systems.
Despite its existence in multiple structural configurations, the compound is characterized as being above the thermodynamic hull. This suggests that while it can be synthesized or observed in specific conditions, it lacks the long-term stability found in ground-state materials.
Key Properties
Cross-validated computational properties for Hg1Pb2Sn1, 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.
