· Ta2Tl4S11

Ta2Tl4S11 is a ternary chalcogenide semiconductor compound combining tantalum, thallium, and sulfur. This is a research-stage material studied primarily for its potential in optoelectronic and photovoltaic applications, where layered sulfide semiconductors offer tunable bandgaps and interesting optical properties. The material family remains largely experimental, with applications under investigation in thin-film solar cells, infrared detectors, and solid-state devices where alternative chalcogenides like CdS or CIGS are conventional choices.
