TiFeSe
TiFeSe is a semiconducting iron-based ternary compound that exists as a metastable phase within the iron-chalcogenide materials family.
About TiFeSe
TiFeSe is a ternary iron-based compound that occupies a distinct position within the broader family of iron-chalcogenide materials. Characterized by its semiconducting electronic nature, it serves as an intriguing subject for structural analysis within the iron-based superconductor class.
Despite its status as a metastable phase residing above the thermodynamic hull, TiFeSe is notable for its structural diversity, with multiple reported configurations across materials databases. This complexity makes it a valuable case study for understanding phase stability and structural evolution in iron-based systems.
Key Properties
Cross-validated computational properties for TiFeSe, 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.

How It Compares
Within the iron-based superconductors class.
Unlike the highly studied and stable FeSe, which is a cornerstone of iron-based superconductivity research, TiFeSe is a less common phase that lacks the established superconducting properties of its siblings like FeSe or FeTe2, primarily due to its metastable nature and semiconducting behavior.
