BeInSi2
BeInSi2 is a metallic ternary compound containing beryllium, indium, and silicon that is currently studied for its structural complexity and metastable nature.
About BeInSi2
BeInSi2 is a complex ternary compound composed of beryllium, indium, and silicon. Its electronic character is defined by metallic behavior, indicating a lack of a band gap and potential for conductive applications in specialized materials research. The compound has been identified across multiple structural databases, reflecting significant interest in its atomic arrangement despite its complex nature. Due to its position relative to the thermodynamic hull, it is considered a metastable phase that requires specific synthesis conditions to be realized. Its study contributes to the broader understanding of ternary systems involving light alkaline earth metals and heavy post-transition metals.
Key Properties
Cross-validated computational properties for BeInSi2, aggregated across 5 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.
