Gallium arsenide (GaAs) is a compound of the elements gallium and arsenic. It is a III/V semiconductor and is used in the manufacture of devices such as microwave frequency integrated circuits monolithic microwave integrated circuits infrared light-emitting diodes laser diodes solar cells and optical windows.GaAs is often used as a substrate material for the epitaxial growth of other III-V semiconductors including: InGaAs and GaInNAs.
