Abstract
The deposition of 1-3 monolayers of Ni or Ag on benzene adsorbed on a W(110) surface at 90 K was studied by XPS, Auger, work function, UPS, and thermal desorption measurements. It was found that Ni penetrates b enzene multilayers to some extent but shows some vestiges of ordered g rowth underneath benzene. Ag penetrates more than Ni and does not grow layer by layer-but forms clusters. It is hypothesized that the differ ences between Ni and Ag arise from the much weaker interaction of Ag w ith benzene.
