Gallium

Gallium (Ga) is a metal which does not form distinct minerals, but substitutes for aluminum in the structure of many aluminum-bearing minerals. Gallium arsenide (GaAs) is the principal compound used in light-emitting diodes, photodetectors, laser diodes, and solar cells. An important potential application incorporates gallium compounds in diodes in bar-code scanners used in grocery stores.
