· JVASP-155402· HfCu2HgS4

HfCu2HgS4 is a quaternary intermetallic compound combining hafnium, copper, mercury, and sulfur—a complex metal-based material that bridges metallic and chalcogenide chemistry. This is a research-phase compound with limited commercial production; it belongs to the family of ternary and quaternary metal sulfides that are investigated for potential applications in thermoelectrics, semiconductors, and solid-state devices where the combination of heavy elements (Hf, Hg) and transition metals (Cu) can produce unusual electronic and thermal properties.
