Preparation of Solid Solutions of GaP and GaAs by a Gas Phase Reaction

Homogeneous solid solutions of gallium phosphide and gallium arsenide were synthesized. The synthesis involves the transport of the constituents of the solid solution to a cool substrate by means of a complex reaction with iodine under near‐equilibrium conditions. The homogeneity of the samples prepared was demonstrated by x‐ray, microscopic, and optical absorption measurements.
