Te0.6Se0.4

Te0.6Se0.4 is a tellurium-selenium alloy semiconductor compound that combines tellurium (60%) and selenium (40%) to form a narrow-bandgap material. This material is primarily explored in research and niche industrial applications for infrared detection and sensing, where its sensitivity to thermal radiation and ability to operate in the mid-to-far infrared spectrum make it valuable for thermal imaging, radiometric measurement, and environmental monitoring. The tellurium-selenium system is notable for its tunable bandgap through compositional variation, offering advantages over pure tellurium or selenium in balancing sensitivity, temperature stability, and manufacturability for specialized optoelectronic devices.
