21.D1 Gallium arsenide (GaAs) and gallium phos- phide (GaP) are compound semiconductors that have room-temperature band gap energies of 1.42 and 2.26 eV, respectively, and form solid solutions in all proportions. The band gap of the alloy increases approximately linearly with Gap additions (in mol%). Alloys of these two materi- als are used for light-emitting diodes wherein light is generated by conduction band-valence band
