LiPb2Y
LiPb2Y is a semimetallic ternary compound of lithium, lead, and yttrium that exhibits structural complexity despite its thermodynamic instability.
About LiPb2Y
LiPb2Y is a complex ternary compound composed of lithium, lead, and yttrium. Exhibiting a near-zero-gap electronic character, this material functions as a semimetal, placing it in a unique position between metallic and semiconducting behaviors.
Because this compound sits above the thermodynamic hull, it is considered likely unstable under standard conditions. Despite this, its structural diversity is evidenced by multiple reported entries across various crystallographic databases, reflecting significant interest in its atomic configuration.
Key Properties
Cross-validated computational properties for LiPb2Y, 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.
