TiF2
TiF2 is a semiconducting titanium fluoride compound that is often studied for its complex structural properties and metastable nature.
About TiF2
TiF2 is a binary fluoride of titanium that exhibits semiconducting electronic behavior. As a material of interest in fundamental inorganic chemistry, it has been the subject of extensive structural investigation across multiple databases, reflecting its complexity and the challenges associated with its synthesis and characterization.
Due to its position relative to the thermodynamic hull, this compound is considered metastable, which makes it a compelling subject for researchers exploring high-pressure phases or non-equilibrium synthesis techniques. Its existence as a semiconducting fluoride distinguishes it from more common, highly insulating metal fluorides.
Key Properties
Cross-validated computational properties for TiF2, 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.
