Gallium arsenide
While silicon is the prevalent material for wafers used in the electronics industry, other compound III-V or II-VI materials have also been employed. Gallium arsenide (GaAs), a III-V semiconductor produced via the Czochralski process, Gallium nitride (GaN) and Silicon carbide (SiC), are also common wafer materials, with GaN and Sapphire being extensively used in LED manufacturing.
