Oxide semiconductor targets

Oxide semiconductor targets consist of compounds composed of oxygen and one or more additional elements, typically metals. These compounds exhibit a wide range of electronic properties, making them valuable for various electronic and optoelectronic applications. Some notable examples of oxide semiconductor targets include IGZO (Indium Gallium Zinc Oxide), SrRuO3 (Strontium Ruthenate), and In2O3:Cu (Copper-Doped Indium Oxide).
