Tl2 In2 Se4
semiconductor· Tl2 In2 Se4
Tl₂In₂Se₄ is a ternary semiconductor compound combining thallium, indium, and selenium in a layered crystal structure, belonging to the class of III–VI chalcogenides. This material is primarily of research interest for optoelectronic and infrared sensing applications, where its tunable bandgap and anisotropic properties offer potential advantages over conventional binary semiconductors like InSe or GaSe. The material family is notable for strong light-matter interactions and potential use in next-generation photonic devices, though commercial deployment remains limited compared to established semiconductor platforms.
