摘要：
We calculate (to first order in the Burgers vector) the energy of introducing dislocations into Stranski-Krastanow islands having equilibrium shape. These results suggest that misfit dislocations of different Burgers vector tend to segregate spatially within the islands, which may be a source of mosaic structure in films formed by island coalescence.
