About I2O2Tm2
I2O2Tm2 is a complex inorganic compound composed of thulium, iodine, and oxygen. As a thermodynamically stable phase residing on the convex hull, it represents a robust structural arrangement within its chemical system.
This material exhibits a wide-band-gap insulating electronic character, which is characteristic of many lanthanide-based oxyhalides. Its stable nature makes it a subject of interest for researchers investigating the fundamental interactions between rare-earth elements and chalcogen-halogen frameworks.
Key Properties
Cross-validated computational properties for I2O2Tm2, 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.
