  text: When strained Stranski-Krastanow islands are used as "self-assembled
    quantum dots," a key goal is to control the island position. Here we show
    that nanoscale grooves can control the nucleation of epitaxial Ge islands on Si(001),
    and can drive lateral motion of existing islands onto the grooves, even when the
    grooves are very narrow and shallow compared to the islands. A position centered
    on the groove minimizes energy. We use as prototype grooves the trenches which
    form naturally around islands. During coarsening, the shrinking islands move laterally
    to sit directly astride that trench. In subsequent growth, we demonstrate that
    islands nucleate on the "empty trenches" which remain on the surface
    after complete dissolution of the original islands.
