Whatever happened to Gallium-Arsenide?

Gallium-Arsenide (GaAs) is a compound semiconductor of Gallium (Ga) and Arsenic (As). Gallium is rarer than gold. Arsenic isn't rare, but yeah, it's poisonous. GaAs is a faster conveyor of current than silicon. And, GaAs IC's consume less power. But GaAs is significantly more expensive and harder to come by than silicon. read more

Gallium arsenide (GaAs) is a compound of the elements gallium and arsenic. It is an important III/V semiconductor, and is used in the manufacture of devices such as microwave frequency integrated circuits, e.g., monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells, and optical windows. read more
