Li5Si2BiO8
Li5Si2BiO8 is a metastable, semiconducting oxide composed of lithium, silicon, bismuth, and oxygen.
About Li5Si2BiO8
Li5Si2BiO8 is a complex oxide containing lithium, silicon, bismuth, and oxygen. As a semiconducting material, it exhibits electronic properties that distinguish it from simple insulating oxides, making it a subject of interest for fundamental materials science exploration.
Although it is classified as a metastable phase, the existence of multiple reported structures across various databases highlights its structural diversity. This compound serves as a valuable case study for understanding phase stability and the complex bonding environments present in multi-component lithium-based oxides.
Key Properties
Cross-validated computational properties for Li5Si2BiO8, 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.
