Secondary Electron Emission by Plasmon Induced Symmetry Breaking in Highly Oriented Pyrolitic Graphite (HOPG)

Wolfgang S. M. Werner, Vytautas Astašauskas, Philipp Ziegler +4

Two-particle spectroscopy with correlated electron pairs is used to establish the causal link between the secondary electron spectrum, the $(\pi +\sigma )-$plasmon peak and the unoccupied b…
