gallium arsenide
An alloy of gallium and arsenic compound (GaAs) that is used as the base material for chips. Several times faster than silicon, it is used in high frequency applications such as cellphones, DVD players and fiber optics. In 2001, Motorola developed a technique that places a spongy layer between gallium arsenide and silicon on the same wafer. Combining these two materials yields a higher-speed product at a lower cost. See gallium nitride.
gallium arsenide [′gal·ē·əm ′ärs·ən‚īd]
(inorganic chemistry)
GaAs A crystalline material, melting point 1238°C; frequently alloys of this material are formed with gallium phosphide or indium arsenide.

These processes are used in the formation of GaAs Laser diode, LED, HgCdSb high efficiency solar devices, GaAs HBT, GaAs MESFET and pHEMT.
The process is entirely electronic, through the GAAS scholarship website, www.
The Strategy Analytics GaAs and Compound Semiconductor Technologies (GaAs) service has released, "Point-to-point Radio GaAs Component Demand from Cellular Backhaul," forecasting that GaAs revenues from this market will flatten from 2008 onwards corresponding to slowing unit shipment growth of point-to-point radios used for cellular backhaul.
