· JVASP-155466· TlAg2SbS4

TlAg₂SbS₄ is a quaternary semiconductor compound belonging to the metal sulfide family, combining thallium, silver, and antimony chalcogenides. This is a research-phase material primarily investigated for photovoltaic and thermoelectric applications due to its semiconducting properties and layered crystal structure. Its potential lies in solid-state energy conversion devices where the combination of heavy metal elements may offer favorable band gap engineering and phonon scattering characteristics compared to binary or ternary alternatives.
