Zn0.65Hg0.35Se

Zn₀.₆₅Hg₀.₃₅Se is a cadmium-free II-VI semiconductor alloy combining zinc selenide and mercury selenide, engineered for infrared detection and imaging applications where tunable bandgap is critical. This mercury-containing compound is used primarily in specialized optoelectronic devices operating in the mid-to-long wavelength infrared spectrum, particularly where narrower bandgap control is needed compared to pure ZnSe. The material represents a research-focused composition rather than a mainstream industrial standard, selected for its bandgap engineering properties in high-sensitivity photodetectors and thermal imaging systems where mercury alloying enables wavelength tunability.
