· Te4 Mo1 W3 Se2 S2

Te₄Mo₁W₃Se₂S₂ is a mixed-chalcogenide semiconductor compound combining tellurium, molybdenum, tungsten, selenium, and sulfur. This is a research-stage material rather than a commercial product, belonging to the family of polymetallic chalcogenides that are studied for their tunable band gaps, layered crystal structures, and potential for charge-carrier engineering.
