Cd₀.₃₅Hg₀.₆₅Te is a cadmium-mercury-telluride (CdHgTe) ternary alloy semiconductor with tunable bandgap energy determined by its cadmium-to-mercury composition ratio. This material is primarily used in infrared detection and thermal imaging applications, where its narrow bandgap enables sensitivity in the mid-wave to long-wave infrared spectrum (3–14 μm), making it the industry standard for high-performance thermal cameras, forward-looking infrared (FLIR) systems, and scientific spectroscopy instruments. CdHgTe is chosen over single-element semiconductors because its adjustable composition allows precise engineering of bandgap energy for specific infrared wavelengths without requiring lattice-matched substrates, though its toxicity and cost limit adoption to high-value military, aerospace, medical imaging, and research applications.
