HC
HC is a metastable hydrocarbon material characterized by its insulating electronic properties and a diverse array of potential structural configurations.
About HC
HC is a metastable hydrocarbon composition that represents a complex structural landscape in materials science. Due to the high number of reported structural configurations, it serves as a significant subject for studying carbon-hydrogen bonding arrangements and phase stability.
As a wide-band-gap insulating material, it possesses unique electronic properties that distinguish it from conductive carbon allotropes. Its metastable nature makes it a fascinating target for synthesis research and high-pressure experimental studies.
Key Properties
Cross-validated computational properties for HC, aggregated across 4 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.
