LiMgBi
LiMgBi is a stable, semiconducting ternary compound containing lithium, magnesium, and bismuth.
About LiMgBi
LiMgBi is a ternary compound composed of lithium, magnesium, and bismuth. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration of these elements that is of significant interest for structural and electronic studies.
This material exhibits semiconducting electronic character, making it a subject of investigation for potential applications in solid-state electronics and thermoelectric devices. Its existence across multiple reported structures highlights its versatility and the importance of understanding its phase behavior in materials science.
Key Properties
Cross-validated computational properties for LiMgBi, aggregated across 3 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Reported Structures
Lowest-energy structures reported for LiMgBi, ranked by energy above hull.
| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom. Use energy above hull, not this value alone, when comparing stability. | Density (g/cm³)Mass per relaxed crystal volume, reported in grams per cubic centimeter. |
