The diffusion of iron in indium phosphide is found to proceed via the kick-out diffusion mechanism. A Fe diffusion profile in InP available from the literature is simulated using the complete set of three partial differential equations for the kick-out mechanism. A value for the contribution of indium self-interstitials to the self-diffusion coefficient of InP is extracted and found to be much smaller than the known self-diffusion coefficient determined from indium tracer diffusion measurements. Possible reasons for the observed difference are discussed. Furthermore, an analogy of diffusion in InP to diffusion in GaAs is suggested
