The interaction of Ag with a (√3 √3)R30-Au/Si(111) interface containing three-dimensional (3D) Au microparticles has been studied by means of synchrotron radiation photoelectron microspectroscopy and elemental imaging with spatial resolution of 150 nm. The evolution of the space-resolved core-level spectra from the √3-Au and 3D phases has revealed the impact of the surface morphology on the local...
The interaction of a (3 3)R30°-Ag/Si(111) interface, containing Ag agglomerates, with Au coadsorbed at 300 K has been studied by means of scanning photoelectron microscopy and low-energy electron diffraction. The high lateral resolution provided by the microscope allowed detailed examination of the local composition and reactivity of the coexisting surface phases. A substantial difference in...
