GaAs Wafers
Gallium Arsenide (GaAs) wafers are critical components in modern electronics and photonics due to their superior electrical and optical properties.
Here�¢??s a focused overview:
GaAs�¢?? is shorthand for Gallium Arsenide, a compound made up of two elements, and the semiconductor used to manufacture GaAs wafers. GaAs is used as a direct bandgap semiconductor, which in layman�¢??s terms, simply means that particles such as electrons can pass through components much quicker and with very little interference. This makes them particularly useful in optical devices because photons, the basic unit for all light, can pass through lenses with ease.
What are GaAs Wafers Use For?
The use of GaAs wafers is dictated by the capabilities of the compound. Because GaAs is a direct bandgap semiconductor, it is especially useful in sensitive electronic equipment that requires amplifying low frequencies. Some of the most common applications for GaAs wafers include:
Supplier: Vacuum & precision groups of semiconductor and electric industry. Services: Repairing of vacuum & precision groups of semiconductor and electric industry
