    • note
    • A 7.0 Å cluster radius is, e.g., sufficient to ensure in the whole QM zone a <0.1 eV/Å rms deviation from the exact TB forces in a 0.5 ps LOTF simulation of a vacancy diffusion event in a 215 Si atom system at 1400 K. Constructing clusters of similar size including all Si atoms up to a chosen neighbor shell rather than up to a fixed radius yields analogous results. We note that for the purposes of this study we restrict ourselves to systems where long range forces do not appear.

    • We obtained analogous results for the diffusion of the Si self-interstitial, for which the SW potential fails to predict the correct 0 K structure.
