WI4
Tungsten tetraiodide is a thermodynamically stable semiconducting compound composed of tungsten and iodine.
About WI4
Tungsten tetraiodide is a semiconducting inorganic compound that occupies a stable position on the thermodynamic convex hull. Its existence as a well-defined phase highlights the complex coordination chemistry possible between tungsten and halogen elements.
This material is of interest to researchers studying the fundamental electronic properties of transition metal halides. Its stability makes it a significant subject for structural investigations into how tungsten-iodine bonding influences semiconducting behavior.
Key Properties
Cross-validated computational properties for WI4, aggregated across 2 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.
