Abstract

Pb nucleation on top of a unique Pb island grown on Si(7x7) (in the form of a "hub"-"moat"-ring) confirms that electron confinement causes large variations in critical size cluster i(c) with island height. Because of smaller radial dimensions (less than 20 nm), the large variation of the nucleated island density on different layers cannot be a result of differences in terrace diffusion coefficients but ic. These results have important implications on how adsorption can be dramatically modified by quantum size effects. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3121504]
