About BeLi2O4Si
BeLi2O4Si is a complex quaternary oxide characterized by its wide-band-gap insulating nature. As a thermodynamically stable phase residing on the convex hull, it represents a robust crystalline arrangement of beryllium, lithium, oxygen, and silicon atoms.
Its inherent stability and electronic properties make it a subject of interest for fundamental materials research. The material serves as a stable building block for exploring the interplay between alkaline earth and alkali metal cations within a silicate framework.
Key Properties
Cross-validated computational properties for BeLi2O4Si, 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.
Cross-Source DFT Agreement
