· Tl1 Cu4 S3

Tl₁Cu₄S₃ is a ternary semiconductor compound combining thallium, copper, and sulfur into a mixed-metal chalcogenide structure. This material belongs to the family of copper-based sulfide semiconductors and is primarily of research interest rather than established in high-volume industrial production. The compound is investigated for potential applications in thermoelectric devices, photovoltaic absorbers, and optoelectronic components, where its layered crystal structure and tunable electronic properties may offer advantages over conventional binary semiconductors.
