We use the Stillinger-Weber potential to calculate the energy barriers for a large number of atomic jumps on the Si(100)-2 × 1 surface. These calculations take into account the reconstruction of the surface and the effect of the atoms occupying the neighboring sites. We isolate the set of jumps through which the adsorbed Si atoms aggregate to form the string-like islands observed experimentally.
