About BaSrI4
BaSrI4 is a complex quaternary iodide characterized by its wide-gap insulating electronic structure. As a material that sits near the thermodynamic hull, it is considered a prime candidate for experimental synthesis and structural characterization.
Its significance lies in its potential utility within specialized optical applications where wide-gap materials are required to manage high-energy interactions. The compound is actively studied for its structural diversity, supported by a substantial body of reported structural data.
Key Properties
Cross-validated computational properties for BaSrI4, 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.
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.
