· Al2 Se4 Tl2

Al₂Se₄Tl₂ is a mixed-metal selenide semiconductor compound combining aluminum, selenium, and thallium elements. This is a specialized research material rather than an established commercial compound, belonging to the family of ternary and quaternary semiconductors being investigated for optoelectronic and thermoelectric applications. The material's potential lies in photonic devices, radiation detection, or thermal-to-electric energy conversion where the band structure and charge carrier properties of mixed-cation selenides offer advantages over conventional binary semiconductors.
