CaBiB
CaBiB is a semimetallic ternary compound of calcium, bismuth, and boron that exists in a metastable state.
About CaBiB
CaBiB is a ternary inorganic compound composed of calcium, bismuth, and boron. Its electronic character is defined as near-zero-gap, placing it in the semimetallic regime, which makes it an intriguing subject for fundamental studies in condensed matter physics.
Due to its position above the thermodynamic hull, this material is considered likely unstable under standard conditions. Despite this, it remains a notable subject of interest within structural databases, where multiple distinct configurations have been documented for further investigation.
Key Properties
Cross-validated computational properties for CaBiB, 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.
