BF2
BF2 is a metastable, wide-band-gap insulating compound composed of boron and fluorine that is frequently analyzed in theoretical structural studies.
About BF2
BF2 is a binary inorganic compound composed of boron and fluorine. It is characterized as a wide-band-gap insulator, placing it firmly within the category of dielectric materials that resist electrical conduction under standard conditions.
Due to its position above the thermodynamic hull, this compound is considered metastable. Despite its inherent instability, it remains a subject of significant interest in computational materials science, with numerous structural configurations documented across major research databases.
Key Properties
Cross-validated computational properties for BF2, 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.
