The interaction between Zn atoms and Pd(100) single crystal surface has been studied
by electron spectroscopic methods. The broadening of the Pd (3d5/2) XPS signal (X-ray
Photon Electron Spectroscopy) gave us the opportunity to calculate the enthalpy of
alloy formation between Pd and Zn.
The advantage of this methods is that one could investigate the interaction between
the two metals whether in nano meter size, small amount or even bulk. The separation
of these particles or in the presence of other metals, chemical elements, catalysts
support are less important. Another benefit is that beside the XPS spectroscopy one
could combine them by Auger-,ultraviolet photoelectron work function measurements
and mass spectroscopy.
