Abstract
The ability to create an ensemble of mono-dispersed nanostructures is an important step towards the realization nanotechnology. The discovery of surface-magic-clusters (SMC), i. e. clusters exhibiting enhanced stability at certain sizes on a particular surface, has opened up the possibility of exploiting SMC formation for the growth of identical nanostructures on surfaces. Recently, it has been demonstrated that, under a well controlled deposition condition, several group III elements such as gallium can induce almost exclusive formation of SMC on the 7x7-reconstructed Si(111) surface, leading to the complete filling of the 7x7 half unitcells and the creation of unprecedented two-dimensional lattices of SMC. Based on scanning tunneling microscopy imaging studies, structure models for the SMC are proposed. Ab inito calculations of the model clusters are conducted and the results are compared with experiments.
