· Tl4Ta2S11

Tl₄Ta₂S₁₁ is a mixed-metal sulfide semiconductor compound combining thallium and tantalum elements in a layered crystal structure. This is a research-phase material primarily investigated for optoelectronic and photovoltaic applications due to its tunable bandgap and layered geometry; it belongs to the family of transition metal chalcogenides that show promise for next-generation thin-film solar cells, photodetectors, and quantum devices where conventional semiconductors face performance or cost limitations.
