Bonding Configurations and Collective Patterns of Ge Atoms Adsorbed on Si(111)-7x7

Y. L. Wang, H. -J. Gao, H. M. Guo +2

We report scanning tunneling microscopy observations of Ge deposited on the Si(111)-7x7 surface for a sequence of sub-monolayer coverages. We demonstrate that Ge atoms replace so-c…
