Aluminum Gallium Arsenide (AlGaAs) is a crystalline solid used as a semiconductor and in photo optic applications. An arsenide, an anion with the charge -3, is a rare mineral group consisting of compounds of one or more metals with arsenic (As). Arsenide anions have no existence in solution since they are extremely basic. Gallium arsenide (chemical formula GaAs) is a semiconductor compound used in some diode s, field-effect transistor s (FETs), and integrated circuit s (ICs). The charge carriers, which are mostly electron s,move at high speed among the atom s. This makes GaAs components useful at ultra-high radio frequencies, and in fast electronic switching applications.
Since the early s, scientists have been promoting gallium arsenide as a faster, more efficient substrate material than silicon for making integrated-circuit chips. However, the vast majority of chips are still made from silicon, which is abundant and cheap. The most important advantage of gallium arsenide is speed. Electrons travel about five times faster in gallium arsenide than they .
