Aluminium gallium arsenide

Aluminium gallium arsenide is a semiconductor material with very nearly the same lattice constant as GaAs, but a larger bandgap Band gap

In solid state physics [i] and related applied fields, the band gap is the energy difference between the ... 

. The x in the formula above is a number between 0 and 1 - this indicates an arbitrary alloy Alloy

An alloy is a combination, either in solution [i] or compound [i], of two or more elements [i] ... 

 between GaAs and AlAs Aluminium arsenide

Aluminium arsenide, AlAs, is a semiconductor material [i] with almost the same lattice constant [i] as GaAs [i] ... 

. The bandgap varies between 1.42 eV  and 2.16 eV . For x < 0.4, the bandgap is direct. The formula AlGaAs should be considered an abbreviated form of the above, rather than any particular ratio. Aluminium gallium arsenide is used as a barrier material in GaAs based heterostructure devices.
