By exploring the interplay between potassium, tin, and antimony, scientists seek to leverage its unique chemical framework to overcome limitations found in traditional halide-based systems.
Key Properties
Cross-validated computational properties for K3SnSb3, 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.
