· JVASP-99732· CdHg3Te4

CdHg₃Te₄ is a ternary semiconductor ceramic compound composed of cadmium, mercury, and tellurium, belonging to the II-VI semiconductor family. This material is primarily investigated for infrared detection and thermal imaging applications, where its narrow bandgap enables sensitivity in the mid- to long-wave infrared spectrum. It represents an advanced alternative to simpler binary compounds like HgCdTe, offering potential for tuned optoelectronic performance in specialized sensing systems, though it remains largely in research and development rather than mainstream industrial production.
