About BiB
BiB is a binary compound composed of bismuth and boron that exhibits near-zero-gap electronic character, placing it in the category of semimetallic materials. Its electronic structure suggests unique transport properties that are of interest for fundamental condensed matter research.
Due to its position above the thermodynamic hull, this compound is considered metastable or unstable under ambient conditions. Despite this, it has been the subject of extensive structural investigation, with over one hundred distinct configurations reported across major materials databases.
Key Properties
Cross-validated computational properties for BiB, 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.
