· Li4 S6 U2

Li₄S₆U₂ is an experimental semiconductor compound combining lithium, sulfur, and uranium in a mixed-valence system. This is a research-phase material rather than a commercial product, belonging to the family of uranium-bearing chalcogenides being investigated for their unique electronic and thermal properties. Interest in this compound stems from potential applications in advanced nuclear materials, solid-state ion conductors, and specialized semiconducting devices where the coupled behavior of uranium f-electrons and sulfide chemistry creates properties unavailable in conventional semiconductors.
