GaAs

Gallium arsenide (GaAs) is a compound synthesized by two elements of gallium and arsenic. It is an important group IIIA and group VA compound semiconductor material. 

Gallium arsenide(GaAs) can be used to make microwave integrated circuits, infrared light-emitting diodes, semiconductor lasers and solar cells. GaAs is often used as the base material for the epitaxial growth of III-V semiconductors, including indium gallium arsenide, aluminum gallium arsenide, and so on.

The advantages include:

▪ Very high electron mobility.

▪ GaAs cells are relatively insensitive to heat compare to silicon cells. Hence it offers high thermal stability.

▪ Lower noise.

▪ Operates over wide temperature range.

▪ High efficiency and resistance to radiation.
