Cadmium germanate (CdGeO3) is an inorganic compound semiconductor belonging to the class of metal oxide semiconductors, synthesized primarily for research and specialized optoelectronic applications. While not widely commercialized, this material is investigated for potential use in photonic devices, radiation detection, and high-refractive-index optical components due to the electronic properties imparted by its cadmium and germanium constituents. Engineers consider CdGeO3 in advanced materials research when conventional semiconductors (silicon, gallium arsenide) do not meet requirements for specific wavelength ranges or when the high density and mechanical stiffness of metal oxides are advantageous for radiation-hardened or high-temperature sensing applications.
