Interdiffusion in the InPGaP solid solution system is investigated by means of X‐ray diffraction of annealed powder blends. An activation energy of Q = (3.15 ± 0.3) eV for the interdiffusion process in the temperature interval 650… 725 °C was found. Diffusion parameters obtained by means of this method for InPGaP and InAsGaAs are discussed on the basis of lattice and atomic characteristics.
