· JVASP-80575· Tl2HgTe

Tl2HgTe is a ternary compound semiconductor ceramic composed of thallium, mercury, and tellurium. This material belongs to the family of narrow-bandgap semiconductors and is primarily of research and specialized optoelectronic interest rather than mainstream industrial production. The compound is notable for its potential in infrared detection and imaging applications where narrow-bandgap materials enable sensitivity in the mid- to long-wavelength infrared spectrum, though it remains less common than competing alternatives like HgCdTe due to thallium toxicity concerns and processing complexity.
