Tl1 Cd1 Se2

TlCdSe₂ is a ternary II-VI semiconductor compound combining thallium, cadmium, and selenium. This material belongs to the narrow-bandgap semiconductor family and is primarily of research interest for infrared detection and optoelectronic applications, where its electronic properties enable sensitivity in wavelength ranges difficult to access with conventional semiconductors like silicon or gallium arsenide. While not widely commercialized in high-volume manufacturing, ternary cadmium-based semiconductors like this are investigated for specialized detection systems and potential thermal imaging devices where conventional alternatives have performance or cost limitations.
