Iodine is a thermodynamically stable, semiconducting element recognized for its significant structural diversity and widespread utility in industrial and chemical processes.
About Iodine
Iodine is a fundamental chemical element that exists as a thermodynamically stable solid under standard conditions. It is characterized by its semiconducting electronic nature, which distinguishes it from many other non-metallic elements and influences its reactivity in various chemical environments.
This element is highly valued for its structural complexity, as evidenced by the large number of reported crystalline arrangements across major databases. Its role as a versatile chemical building block makes it essential for high-performance applications ranging from advanced manufacturing to specialized chemical synthesis.
Key Properties
Cross-validated computational properties for Iodine, 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 I. 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.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
