GdIS
GdIS is a stable, semiconducting ternary compound containing gadolinium, iodine, and sulfur.
About GdIS
GdIS is a semiconducting compound composed of gadolinium, iodine, and sulfur. As a thermodynamically stable material residing on the convex hull, it represents a robust phase within its chemical system.
Its electronic character suggests potential utility in specialized semiconductor applications. With multiple reported structures across various databases, it is a well-documented subject for researchers investigating complex chalcogenide-halide systems.
Key Properties
Cross-validated computational properties for GdIS, 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.
