摘要：

We have studied the growth of ultrathin Ag films on Si(111)7x7 between 80-100 K with low-temperature scanning tunneling microscopy. Nucleation of Ag in both halves of the 7x7 is observed. Comer holes and dimer sites are not occupied. Percolation occurs at submonolayer coverage through contact between the nucleated 2D Ag islands. This results in a honeycomb random site percolation problem. Upon completion of the first monolayer, 2D layer-like growth is observed.
