9. Because the XTEM images are [110] cuts through the islands, the base size corresponds to the diagonal of the <100> aligned base of the pyramidshaped huts.
10. The island spacing is considered to be the distance between the center of two islands.
11. We follow this simplified approach in spite of our observation that the shape of the overgrown islands is boxlike and not well approximated by a single sphere/point source of expansion. But. nevertheless, the physics of the island "interaction" can be understood using this simple model.
