· Ag0.4Cd0.5In2.2Te4

Ag0.4Cd0.5In2.2Te4 is a quaternary semiconductor compound composed of silver, cadmium, indium, and tellurium, belonging to the family of II-VI and I-VI mixed semiconductors. This material is primarily investigated in research contexts for infrared detection and optoelectronic applications, where its bandgap and carrier transport properties position it as a candidate for thermal imaging sensors and long-wavelength photosensors operating in the mid- to far-infrared spectrum. The complex alloying of cadmium telluride with indium and silver enables band structure engineering for wavelength-selective response, offering potential advantages over simpler binary or ternary compounds in applications requiring precise infrared sensitivity tuning.
