· Tl2Hg3Se4

Tl₂Hg₃Se₄ is a ternary semiconductor compound combining thallium, mercury, and selenium in a fixed stoichiometric ratio. This material belongs to the class of chalcogenide semiconductors and is primarily of research interest rather than established commercial use, studied for potential optoelectronic and infrared photonic applications. The material's notable feature is its unique band structure and selenium-based composition, which makes it relevant for investigating narrow-bandgap semiconductor behavior and potential use in specialized detection or photovoltaic devices operating in infrared wavelengths.
