BaCsI3 is a stable, wide-gap insulating inorganic compound consisting of barium, cesium, and iodine.
About BaCsI3
BaCsI3 is a complex inorganic compound composed of barium, cesium, and iodine. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that maintains structural integrity under standard conditions. Its electronic character is defined by a wide-gap insulating nature, which distinguishes its behavior in various solid-state environments.
This material is of significant interest in fundamental materials science due to its well-documented structural diversity. With multiple reported structures across major databases, it serves as a key subject for researchers investigating the interplay between heavy alkaline earth metals and alkali halides in complex lattice systems.
Key Properties
Cross-validated computational properties for BaCsI3, 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.
