  text: SiGe islands move laterally on a Si(001) substrate during in situ postgrowth
    annealing. This surprising behavior is revealed by an analysis of the substrate
    surface morphology after island removal using wet chemical etching. We explain
    the island motion by asymmetric surface-mediated alloying. Material leaves one
    side of the island by surface diffusion, and mixes with additional Si from the
    surrounding surface as it redeposits on the other side. Thus the island moves
    laterally while becoming larger and more dilute.
