Figure 6

Growth of a wedge-like cluster: (a) reconstruction of the first layer of a forming wedge during addition of epi-oriented dimer pairs of the second (001) terrace; plots of atomic structures of a Ge wedge-shaped hut cluster composed by (b) 2 and (c) 6 monoatomic steps and (001) terraces on the WL (the numbering is the same as in Fig. 5; d marks a defect that has arisen because of one translation uncertainty of the left dimer pair position).
