Size-selected Agn and Cun clusters supported on MgO(100) films

  • Conference paper
Book cover The European Physical Journal D

Abstract

Small Ag n (n ≤ 13) and Cu n (n ≤ 7) clusters, generated by sputtering with a new ultrahigh vacuum (UHV)-compatible Xe-ion gun and size-selected by a quadrupole mass spectrometer, are deposited in situ in submonolayer quantities on a magnesium oxide film supported on a molybdenum single crystal. At low substrate temperature (T = 45 K), the measured electron energy loss spectra display characteristic losses within the MgO band gap. These novel results are discussed in terms of electronic transitions and plasmon excitations within the cluster.
