Abstract

Nickel monolayers on the Cu(111) surface have been studied in an attempt to understand metal-metal interface mixing. High resolution energy loss (HREEL) spectra of carbon monoxide is used to monitor the surface by distinguishing between CO adsorption on top and bridge sites of the nickel overlayer. Results are discussed for nickel deposition at temperatures in the range of 300-475 K. Room temperature nickel deposition leads to nickel island formation; at slightly elevated temperatures nickel and copper mix in the first layer ; and by 475 K, nickel becomes significantly covered by copper, the thermodynamically favored configuration.
