BHC is a semiconducting compound containing boron, carbon, and hydrogen that is currently being studied for its diverse structural possibilities.
About BHC
BHC is a complex chemical compound composed of boron, carbon, and hydrogen. As a semiconducting material, it represents a unique intersection of light-element chemistry, drawing interest for its potential electronic properties and structural versatility. Due to its position above the thermodynamic hull, BHC is considered a metastable phase. Its existence across multiple reported structures suggests a rich landscape of atomic configurations that continue to be a subject of investigation in materials science.
Key Properties
Cross-validated computational properties for BHC, aggregated across 2 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of BHC. Tight agreement means computed properties can be trusted without re-running calculations.
Only 1 independent DFT source (jarvis) reports a hull energy for BHC, so cross-source agreement can't be assessed yet.
Reported Structures
Lowest-energy structures reported for BHC, ranked by energy above hull.
| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom.
