Be1Ge1La2
Be1Ge1La2 is a semimetallic ternary intermetallic compound containing beryllium, germanium, and lanthanum.
About Be1Ge1La2
Be1Ge1La2 is a complex ternary compound composed of beryllium, germanium, and lanthanum. Its electronic structure exhibits near-zero-gap characteristics, placing it in the category of semimetallic materials that often bridge the gap between metallic conductors and semiconductors.
Due to its position above the thermodynamic hull, this compound is considered metastable or unstable under standard conditions. Despite this, it remains a subject of interest in structural chemistry, with numerous reported configurations contributing to the broader understanding of ternary phase space.
Key Properties
Cross-validated computational properties for Be1Ge1La2, aggregated across 2 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.
