Reinterpretation of electron-stimulated desorption data from chemisorption systems

摘要: A review of the electron-stimulated-desorption (ESD) literature shows that many features ESD are difficult to rationalize within model Menzel, Gomer, and Redhead can easily be interpreted using Auger decay model, which has recently been developed explain from transition-metal oxide surfaces. Specifically, helps charge state desorbing species, high-energy (\ensuremath{\sim} 30-40 eV) onset behavior is seen, differences in thresholds for positive neutral desorbates, cross-section isotope-effect data, high kinetic energies particles. The success picture ionically bonded surfaces suggests a number new applications ESD, including deduction reaction paths surface chemistry study evolution oxides.
