Abstract

Gallium arsenide antimonide phosphide (GaAsSbP) has been successfully grown on a gallium arsenide substrate by liquid phase epitaxy. A critical amount of phosphorus initially in growth solution is depleted with consequent grading of lattice constant and bandgap in the epitaxially grown layer. The substrate and graded layer as a subassembly are well suited for use in electronic devices such as double heterostructure lasers, light-emitting diodes, Schottky barrier diodes, and p-n junction photodiodes in the near-infrared low loss region of optical fibers.
