The role of C as a suppressor of B, P, and In diffusion is widely known but the mechanisms involved are still poorly understood. This paper presents novel results on the diffusion of C at the nanometer scale, which clearly show that the suppression of diffusion arises from the expulsion of interstitials from the Cdoped region, caused by long-range migration of interstitial C atoms. Fundamental parameters for C diffusion (migration frequency and jump length) are presented and compared with existing data for B diffusion, and the results are placed in the context of a unified model of impurity diffusion.
