We present a simple modeling of boron diffusion in Sii_X_yGe„Cy by manipulating the strain and the intrinsic carrier concentration. We show that the diffusion of boron is strongly suppressed by a moderate concentration of substitutional C in Sii_XGex. This suppression is due to an under saturation of Si selfinterstitials in the C-rich region. The results obtained from the proposed model are in good agreement with the measured values.
