About GaAs

Gallium Arsenide (composition format:GaAs),is mainly used as semiconductor device material.
Compared with silicon,GaAs has the disadvantage of high-price and difficult to process etc however due to the high motion fuction and approx 1/3 of consumed electricity therefore it's easier to be downsized.

In recent years,thanks to the development of processing technology,GaAs device can also be provided at a lower price,which is widely used in applications mainly require a small size and high frequency property such like mobile phone,and LED application,laser application.
