Abstract
Be diffusion during post-growth annealing has been studied in InGaAs epitaxial layers. To explain the observed concentration profiles, a General Substitutional-Interstitial model is proposed. A simultaneous diffusion by dissociative and kick-out models is suggested. The concentration dependent diffusivity has also been covered to perforn an improved data fitting of Be diffusion profiles.
