BCl2
BCl2 is a semiconducting boron chloride compound that is primarily studied for its diverse structural configurations despite its thermodynamic instability.
About BCl2
BCl2 is a semiconducting compound composed of boron and chlorine. Its electronic character suggests potential utility in specialized thin-film applications where semiconducting properties are required, though it is characterized as thermodynamically unstable relative to more common phases.
Despite its instability, the compound has been the subject of significant interest in computational materials science, with numerous structural configurations documented across major databases. This high level of data richness reflects ongoing efforts to understand the complex bonding behavior of boron-halogen systems.
Key Properties
Cross-validated computational properties for BCl2, 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.
