摘要：
The microscopic work function distributions of Ag-deposited Pt(111) surfaces and Ag/Pt surface alloy have been studied through local tunneling barrier height (LBH) imaging by means of scanning tunneling microscopy (STM). The difference in microscopic work function between Ag and Pt clusters, in the Ag/Pt surface alloy is much smaller than that between Ag large islands and Pt terraces on a Ag-deposited Pt(111) surface although their Ag coverages as well as macroscopic work functions are the same. This features which occurrs when the dimensions of the clusters are a few nanometers is due to the long-range effect of work function reduction which is observed for the Cs-adsorption surfaces. © 2005 The Japan Society of Applied Physics.
