Li3Bi
Li3Bi is a thermodynamically stable semiconducting intermetallic compound formed from lithium and bismuth.
About Li3Bi
Li3Bi is a distinct intermetallic compound composed of lithium and bismuth. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration within its chemical system, making it a subject of interest for fundamental materials science studies.
The material exhibits semiconducting electronic character, which distinguishes it from purely metallic or insulating phases. Its structural diversity is highlighted by multiple reported configurations across various databases, underscoring its significance in understanding lithium-bismuth phase behavior.
Key Properties
Cross-validated computational properties for Li3Bi, 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 Li3Bi, 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. |
