Hg₀.₇Cd₀.₃Se is a narrow-bandgap semiconductor alloy from the II-VI compound family, formed by substituting mercury and cadmium in mercury cadmium telluride (HgCdTe) lattices. This material is primarily used in infrared (IR) detection systems, particularly in the 8–14 μm wavelength range critical for thermal imaging and long-wavelength IR sensing applications. Its tunable bandgap through mercury-cadmium composition control and room-temperature operability make it valuable for military, aerospace, and industrial thermal imaging systems, though it faces competition from newer uncooled detector technologies in cost-sensitive applications.
