Gallium arsenide is a semiconducting material composed of equal amounts of the elements gallium and arsenic. It is a member of a group of semiconductors commonly referred to as the III–V, the constituents of which are to be found in groups III and V of the periodic table.
Gallium Arsenide (GaAs) is a compound semiconductor: a mixture of two elements, Gallium (Ga) and Arsenic (As). Gallium is a byproduct of the smelting of other metals, notably aluminum and zinc, and it is rarer than gold. Arsenic is not rare, but is poisonous. Disadvantages

Gallium arsenide (GaAs) is a mature, proven RF semiconductor process that offers high frequency performance at low cost. GaAs is useful to 90+ GHz and can provide noise figures in P, L and Sband of dB or lower – all at low cost. GaAs also remains the most economical option for power amplifiers in the 1 to 90 GHz range.

Beginning in the mid1970s, DARPA orchestrated extensive research into the semiconductor material gallium arsenide, which could host faster transistors operating at higher power than could silicon. The work would contribute to subsequent DARPAspurred achievement in .
Aug 23, 2019· Gallium arsenide (GaAs) is a compound built from the elements gallium and arsenic. It is often referred to as a IIIV compound because gallium and arsenic are in the III group and V group of the periodic table, respectively. Figure 1. The gallium arsenide compound. Brown represents gallium and purple represents arsenic.
Gallium arsenide and gallium nitride represent about 98% of gallium consumption in the United States. Gallium has been used in nuclear bombs to stabilize the crystal structure. When painted on ...
Aluminium gallium arsenide (also gallium aluminium arsenide) (Al x Ga 1−x As) is a semiconductor material with very nearly the same lattice constant as GaAs, but a larger bandgap. The x in the formula above is a number between 0 and 1 this indicates an arbitrary alloy between GaAs and AlAs .
