Cd2S
Cd2S is a semiconducting compound composed of cadmium and sulfur that is primarily recognized for its structural complexity within the II-VI material class.
About Cd2S
Cd2S is a binary semiconductor belonging to the II-VI class of materials. It represents a specific stoichiometric arrangement of cadmium and sulfur that has been the subject of extensive structural investigation across multiple databases. Its electronic character positions it within the semiconductor family, though its thermodynamic profile suggests it is metastable compared to other configurations. This compound is of interest to researchers studying the phase space of cadmium-chalcogenide systems. While its stability characteristics distinguish it from more common phases, its structural diversity highlights the complex bonding behavior inherent in II-VI semiconductor materials.
Key Properties
Cross-validated computational properties for Cd2S, 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.

How It Compares
Within the ii-vi semiconductors class.
Unlike the highly stable and widely utilized CdS, which serves as a cornerstone for thin-film photovoltaics, Cd2S resides in a less stable region of the phase diagram. While siblings like CdSe and CdTe are well-characterized for their optoelectronic utility, Cd2S is primarily studied for its structural variety rather than as a standard industrial semiconductor.
