      abstract     = {We compare the initial stages of growth of Ge on Si(111)
                      with Bi as a surfactant and without surfactant. At the
                      beginning of growth, three-dimensional islands with a strain
                      relieving dislocation network at their base are formed in
                      both growth systems. These islands can be regarded as seeds
                      of a flat relaxed Ge layer on Si(111). However, such Ge
                      layer forms at later stages of growth only in the growth
                      with Bi surfactant, while the growing Ge layer without
                      surfactant remains rough. What makes the difference and the
                      success of Bi surfactant mediated epitaxy is the lateral
                      growth and coalescence of the seed islands that cover the
                      entire surface within first 15 bilayers of Ge deposition.
                      This happens due to a kinetic limitation of the
                      incorporation of Ge into the growing layer in the presence
                      of surfactant.},
