· Tl4 Sb4 Se8

Tl₄Sb₄Se₈ is a layered semiconductor compound belonging to the thallium-antimony-selenium family, notable for its van der Waals heterostructure characteristics and potential as a narrow-bandgap material. This composition is primarily studied in research contexts for thermoelectric and optoelectronic applications, where its layered crystal structure and tunable electronic properties offer advantages over conventional semiconductors in specific temperature regimes. The material represents an emerging candidate in the broader family of topologically interesting or highly anisotropic semiconductors, though industrial adoption remains limited compared to established alternatives like Bi₂Te₃ thermoelectrics or conventional III-V semiconductors.
