SrIO
SrIO is a semiconducting strontium-based oxyhalide that exists in a metastable state.
About SrIO
SrIO is an inorganic compound composed of strontium, iodine, and oxygen. It exhibits semiconducting electronic character, positioning it as a subject of interest for researchers investigating specialized electronic materials. Due to its position above the thermodynamic hull, this compound is considered metastable or unstable under standard conditions. Despite this, it remains a notable entry in structural databases, with multiple reported configurations that provide insight into the complex bonding environments of alkaline earth oxyhalides.
Key Properties
Cross-validated computational properties for SrIO, 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.
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.
