· Tl1 Cr1 Se2

Thallium chromium diselenide (TlCrSe₂) is a layered ternary chalcogenide semiconductor combining a post-transition metal (Tl), transition metal (Cr), and chalcogen (Se) in a stoichiometric compound. This material belongs to the broader family of metal chalcogenides and layered van der Waals materials, currently studied primarily in research and development rather than established industrial production. The compound is of interest for its potential in optoelectronic and thermoelectric applications, leveraging the distinctive electronic properties that emerge from its layered crystal structure and the combination of dissimilar metal centers.
