semiconductor· CdS0.55Se0.45
CdS₀.₅₅Se₀.₄₅ is a cadmium chalcogenide semiconductor alloy that combines cadmium sulfide and cadmium selenide in a tuned stoichiometric ratio to achieve intermediate bandgap energy. This II–VI compound is engineered to bridge the bandgap between pure CdS (~2.4 eV) and pure CdSe (~1.7 eV), making it valuable for optical and optoelectronic devices that require sensitivity in the visible-to-near-infrared spectrum. The composition is notable in research and specialized manufacturing contexts for photon detection, scintillation counters, and tunable light-emitting applications where bandgap engineering is critical.
