Abstract
Process for the production of yellow glowing gallium phosphide diodes by a liquid phase epitaxial process in which the substrate is covered with a gallium melt saturated with gallium phosphide, elemental tellurium, oxygen and nitrogen are injected into the melt as dopants, a first layer is grown on the substrate from the melt, and then a zinc containing layer is deposited over the first layer, and the temperatures of the layers are controlled to cause diffusion of the zinc into the first layer to a predetermined depth.
