CF2
CF2 is an insulating carbon-fluorine compound that exhibits structural diversity despite its inherent thermodynamic instability.
About CF2
CF2 is a binary compound composed of carbon and fluorine, characterized by its wide-band-gap insulating electronic profile. Its structural landscape is notably diverse, with numerous reported configurations identified across multiple materials databases.
Despite its structural variety, the compound is identified as being above the thermodynamic hull, suggesting it is inherently unstable under standard conditions. This metastability makes it a subject of significant interest for researchers investigating high-energy chemical pathways and specialized fluorinated precursors.
Key Properties
Cross-validated computational properties for CF2, 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.
