· JVASP-139722· TlAsS

TlAsS is a thallium-arsenic sulfide ceramic compound belonging to the chalcogenide ceramic family. This is a research-phase material studied primarily for its potential in infrared optics and semiconductor applications, where thallium-based chalcogenides are investigated for their tunable bandgaps and thermal properties. The material's significance lies in its potential for specialized optoelectronic devices and infrared sensing systems where conventional ceramics prove inadequate, though industrial adoption remains limited pending further development and demonstration of manufacturing scalability.
