BNCl2
BNCl2 is a metastable nitride semiconductor compound composed of boron, nitrogen, and chlorine that is primarily of interest for fundamental materials research.
About BNCl2
BNCl2 is a specialized compound within the nitride semiconductor family, characterized by its unique incorporation of chlorine into a boron-nitrogen framework. Its electronic structure suggests semiconducting behavior, positioning it as an intriguing subject for fundamental studies in materials science.
Despite its existence in multiple structural configurations across databases, the compound is identified as being above the thermodynamic hull. This indicates that it is likely unstable under ambient conditions, representing a challenging but scientifically valuable phase for researchers investigating metastable materials.
Key Properties
Cross-validated computational properties for BNCl2, 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.

How It Compares
Within the nitride semiconductors class.
Unlike the highly stable and technologically ubiquitous members of the nitride class such as GaN or BN, BNCl2 occupies a more precarious position in the phase space. While GaN and AlN are prized for their robust performance in optoelectronics, BNCl2 serves as a theoretical and experimental outlier that highlights the structural diversity possible when incorporating halides into nitride semiconductor lattices.
