CF
CF is a metastable, wide-band-gap insulating material composed of carbon and fluorine.
About CF
CF is an insulating material composed of carbon and fluorine. Its electronic character is defined by a wide band gap, placing it firmly within the category of electrical insulators. Due to its unique atomic arrangement, it remains a subject of interest in fundamental materials research.
While it exists in numerous reported structural configurations across various databases, it is characterized as being above the thermodynamic hull. This suggests that the compound is inherently metastable, requiring specific synthesis conditions to stabilize its structure compared to more common carbon-fluorine phases.
Key Properties
Cross-validated computational properties for CF, aggregated across 5 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 CF. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
