Energy gap: 1.4ev at room temperature

Its charactistics are very closely related to those of germanium. This is under stable, since Gallium is the third column neighbour and arsenic is the fifth column neighbour of Gallium in the periodic table. The melting point is 13000C, makes the production of gallium arsenide of electronic grade and externally difficult one. Horizontal furnaces using zone refining technique have proved the best, but the resulting material is still is not competitive with silicon and germanium in the purity or structural perfection. It is used for Scotty diodes, light emitting diodes, gun diodes, and lasers.
