ScCuO2
semiconductor· ScCuO2
ScCuO2 is a copper oxide compound doped with scandium, belonging to the class of transition metal oxides with semiconductor properties. This material is primarily of research interest rather than established industrial production, investigated for potential applications in high-temperature electronics, solid-state devices, and materials where combined thermal stability and electrical characteristics are valuable. Its appeal lies in the scandium doping strategy, which can modify the electronic band structure and defect chemistry of copper oxide semiconductors—a family explored for next-generation thermoelectrics, gas sensors, and oxide electronics where conventional materials face thermal or chemical limitations.
