Abstract: The formation, self-assembly, and shape transition of heteroepitaxial islands during Stranski-Kranstonov growth are studied by three-dimensional computer simulations. It is shown that calculations considering surface energy anisotropy and elastic anisotropy reproduce many features of experimental results, and demonstrate the significance of their influence on island formation and self-assembly in epitaxial growth.
