About Sodium iodide
Sodium iodide is a thermodynamically stable inorganic salt that functions as a wide-band-gap insulator. Its electronic structure is characterized by a significant energy gap that prevents electrical conduction under standard conditions, making it an ideal candidate for optical and radiation-detection applications.
Due to its high structural reliability and well-documented physical properties, this compound is a cornerstone in the field of radiation physics. It is frequently utilized in devices that require the conversion of high-energy particles into detectable light pulses, serving as a critical component in diagnostic equipment.
Key Properties
Cross-validated computational properties for Sodium iodide, aggregated across 4 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.
