· Cu2 Ge1 Te3

Cu2GeTe3 is a ternary semiconductor compound combining copper, germanium, and tellurium in a fixed stoichiometric ratio. This material belongs to the chalcogenide semiconductor family and is primarily of research and emerging technology interest rather than established industrial production. The compound is investigated for thermoelectric energy conversion, photovoltaic applications, and potentially infrared optoelectronics, where its band structure and carrier transport properties offer advantages over binary semiconductors in specific temperature or wavelength windows.
