PdS

Palladium sulfide (PdS) is a direct-bandgap semiconductor compound combining palladium and sulfur, belonging to the metal chalcogenide family. While largely in the research phase, PdS is investigated for optoelectronic and photocatalytic applications due to its semiconducting properties and potential for tailoring band structure through nanostructuring. Interest in this material centers on catalysis, photoelectrochemistry, and emerging photonic devices where conventional semiconductors (silicon, GaAs) prove inefficient or incompatible.
