Abstract
We have studied the geometrical structures and atomic distributions in small and intermediate size (⩽512 atoms) SimGem clusters by different optimizing methods. We found out that there is a strong tendency for Ge to segregate onto the surface. This can be attributed to arise from the differences in atomic sizes, surface energies and elastic constants. From those the former two seem to have a bigger effect.
