Cd₀.₄Hg₀.₆Se is a cadmium-mercury-selenium ternary alloy semiconductor belonging to the II-VI compound family, forming a solid solution between cadmium selenide and mercury selenide. This material is primarily of research and specialized device interest, particularly for infrared detection and imaging applications where its tunable bandgap—controlled by adjusting the cadmium-to-mercury ratio—enables sensitivity in the mid- to long-wavelength infrared spectrum. The cadmium-mercury-selenide system is notable for its ability to match lattice parameters with lattice-matched substrates and for thermal stability advantages over mercury cadmium telluride (MCT) in certain temperature ranges, though it remains less widely deployed than MCT due to material handling and toxicity considerations.
