Unusually Fast Mobility of Ag and Nanopatterning

Image

Ag deposited on Si(111)-Ag(√3x√3) at 300 K shows unusually fast mobility. Islands nucleate only on step bunches after  traversing 2μm long  terraces . When mixed substrates are used with both 7x7 and  Ag(√3x√3) present the high mobility can be used for nanopatterning with the nucleated islands exclusively  on  top of the 7x7 regions.
