Abstract of the Disclosure

This invention relates to gallium arsenide-gallium phosphide semiconductor material and has as its principal object the provision of an epitaxial layer of such semiconductor material on a substrate of gallium arsenide semiconductor material for use in injection electroluminescent p-n junction diodes and has as another object the provision of the method for producing an epitaxial layer of semiconductor material on a substrate of dissimilar semiconductor material with a minimum of strain between the substrate and epitaxial layer due to the different lattice constants involved.
Figure descriptions: cover graphic

  • the cross-sectional view of injection electroluminescent p-n junction diode of the present invention.
