Fields of Application for Gallium Arsenide (GaAs)

Gallium arsenide (GaAs) is a compound of the elements gallium and arsenic.
Gallium arsenide (GaAs) is a semiconductor compound. Gallium arsenide (GaAs)  has a high electron velocity and high saturated electron mobility. 
This makes gallium arsenide (GaAs) components are useful in fast electronic switching applications and at ultra-high radio frequencies.
In 1907, the British discovered infrared emmission from gallium arsenide. This was called electroluminescence. Also, gallium arsenide (GaAs) was 
used as a solar cells in space for the Venera 3 mission in 1965, which is the first known operational use of gallium arsenide (GaAs).

Vertical gradient freeze is the most common method to produce GaAs wafers.

Mainly used for circuits, electronics and solar cell applications.

Carbon, silicon, tellurium and zinc are some of the dopants that are used to modify the characteristics and electrical properties of gallium arsenide wafers.

Wafer flatness and surface purity are ensured by highest quality standards.

Boron concentration of gallium arsenide wafers highly depend on the production method.

Gallium arsenide wafers with adequate electrical resistancy prevent high current induction in the circuit.

Mobility of GaAs wafers can be tailored with different doping levels.
